FUSE文件系统开发工具,将内核层面的文件系统开发过程平移到应用层面上来。

	* LIB: fix double reply in readdir operation

	* fusermount: fix uid checking bug.  Patch by Adam Connell

	* KERNEL: fix compile on various RedHat patched 2.4 kernels.
	Patch by Keshava Gowda

2005-01-20  Miklos Szeredi <[e-mail]>

	* KERNEL: provide correct llseek semantics for fuse device (fixes
	a bug on Progeny 2.4.20 kernel).  Reported by Valient Gough

2005-01-20  Miklos Szeredi <[e-mail]>

	* Released 2.2-pre5 (matches kernel 2.6.11-rc1-mm2)

2005-01-18  Miklos Szeredi <[e-mail]>

	* KERNEL ABI: remove GETDIR operation, and add OPENDIR, READDIR
	and RELEASEDIR.  This ends the ugly hack of passing a file
	descriptor to the kernel, and actually makes the code simpler.

2005-01-17  Miklos Szeredi <[e-mail]>

	* Released 2.2-pre4

2005-01-17  Miklos Szeredi <[e-mail]>

	* fusermount: remove capability setting, which was the cause of
	problems for some users.  It seems that FS related capabilities
	are removed by setfsuid(), so this isn't even needed.

2005-01-15  Miklos Szeredi <[e-mail]>

	* fix compilation on 2.4 kernels (reported by Valient Gough)

	* fix failure to unmount bug (found by David Shaw)

	* fusermount: improve parsing of /etc/fuse.conf

2005-01-13  Miklos Szeredi <[e-mail]>

	* Remove 'mount_max' and 'user_allow_other' module options.  These
	are now checked by fusermount, and can be set in /etc/fuse.conf

	* KERNEL: change check for fsid == 0 to capable(CAP_DAC_OVERRIDE)

2005-01-11  Miklos Szeredi <[e-mail]>

	* KERNEL: fix possible inode allocation problem, where
	sizeof(struct inode) is not aligned (found by Mike Waychison)

	* KERNEL: use new follow_link/put_link methods

	* KERNEL: cosmetic fixes

2005-01-10  Miklos Szeredi <[e-mail]>

	* Released 2.2-pre3

2005-01-10  Miklos Szeredi <[e-mail]>

	* Add missing code that was accidently left out

2005-01-09  Miklos Szeredi <[e-mail]>

	* Released 2.2-pre2

2005-01-09  Miklos Szeredi <[e-mail]>

	* Change "uid" mount option to "user_id" to avoid confusion with a
	mount option "uid" commonly used by many filesystems

2005-01-09  Miklos Szeredi <[e-mail]>

	* Released 2.2-pre1

2005-01-09  Miklos Szeredi <[e-mail]>

	* If FUSE is configured in the kernel, don't build it by default

2005-01-07  Miklos Szeredi <[e-mail]>

	* Compile fix by Christian Magnusson

2005-01-05  Miklos Szeredi <[e-mail]>

	* Fix compilation for 2.6.{0-5} kernels

2005-01-04  Miklos Szeredi <[e-mail]>

	* KERNEL: if request is interrupted, still keep reference to used
	inode(s) and file, so that FORGET and RELEASE are not sent until
	userspace finishes the request.

	* remove /{sys,proc}/fs/fuse/version, and instead add an INIT
	request with the same information, which is more flexible,
	simpler, works on embedded systems.

2004-12-16  Miklos Szeredi <[e-mail]>

	* KERNEL ABI: update interface to make it independent of type
	sizes.  This will help on 64 bit architectures which can run
	legacy 32 bit applications.

	* KERNEL ABI: add "len" field to request headers.  This will allow
	sending/receiving requests in multiple chunks.

	* KERNEL: handle file type change more intelligently

	* LIB: "-o debug" option should disable backgrounding (fix by
	Fabien Reygrobellet)

2004-12-13  Miklos Szeredi <[e-mail]>

	* KERNEL: invalidate dentry/attributes if interrupted request
	could leave filesystem in an unknown state.

2004-12-12  Miklos Szeredi <[e-mail]>

	* KERNEL: lots of cleanups related to avoiding possible deadlocks.
	These will cause some regressions, but stability is considered
	more important.  If any of these features turns out to be
	important, it can be readded with the deadlock problems addressed.

	* Make all requests interruptible (only with SIGKILL currently).
	This can be used to break any deadlock produced by the userspace
	filesystem accessing it's own exported files.  The RELEASE request
	is special, because if it's interrupted before sending it to
	userspace it is still sent, but the reply is not awaited.

	* If request is interrupted before being sent to userspace, and if
	it hasn't yet got any side effects, it is always restarted,
	regardless of the SA_RESTART flag.  This makes these interruptions
	transparent to the process.

	* Remove shared-writable mmap support, which was prone to an
	out-of-memory deadlock situation

	* Remove INVALIDATE userspace initiated request

	* Make readpages() synchronous.  Asynchronous requests are
	deadlock prone, since they cannot be interrupted.

	* Add readv/writev support to fuse device operations

	* Remove some printks, which userspace FS can use for a DoS
	against syslog

	* Remove 'large_read' mount option from 2.6 in kernel, check it in
	fusermount instead

	* LIB: improve compatibility with a fuse.h header installed in
	${prefix}/include which in turn includes the real header.

	* LIB: improve compatibility by defining fuse_main() (which is now
	not used), so old configure scripts find it.

2004-12-10  Miklos Szeredi <[e-mail]>

	* When mounting on a subdirectory of / don't duplicate slashes at
	the beggining of path (spotted by David Shaw)

2004-12-09  Miklos Szeredi <[e-mail]>

	* Fix bug causing garbage in mount options (spotted by David Shaw)

2004-12-07  Miklos Szeredi <[e-mail]>

	* Add 'writepage' flag to 'fuse_file_info'.

	* More comments in fuse.h

	* Get rid of double underscores

2004-12-04  Miklos Szeredi <[e-mail]>

	* Add -D_FILE_OFFSET_BITS=64 to cflags provided by pkg-config

	* helper.c: add -ho option, which only displays the options not
	the usage header.  This can be used by filesystems which have
	their own options.

2004-12-03  Miklos Szeredi <[e-mail]>

	* Add source compatibility to 2.1 and 1.1 APIs.  To select betwen
	versions simply define FUSE_USE_VERSION to 22, 21 or 11 before
	including the fuse header

	* Add binary compatibility to 2.1 version of library with symbol
	versioning

2004-12-03  Miklos Szeredi <[e-mail]>

	* Released 2.1

2004-12-01  Miklos Szeredi <[e-mail]>

	* kernel: clean up writing functions

	* kernel: no allocation on write in direct_io mode

	* move linux/fuse.h to fuse_kernel.h

2004-11-30  Miklos Szeredi <[e-mail]>

	* kernel: clean up reading functions

2004-11-29  Miklos Szeredi <[e-mail]>

	* kernel: make readpage() uninterruptible

	* kernel: check readonly filesystem flag in fuse_permission

	* lib: don't die if version file not found and new style device
	exists

	* lib: add '-r' option, which is short for '-o ro'

	* fusermount: simplify device opening

	* kernel: when direct_io is turend on, copy data directly to
	destination without itermediate buffer.  More efficient and safer,
	since no allocation is done.

	* fusermount: fix warning if fuse module is not loaded

	* kernel: use /dev/fuse on 2.4 too

2004-11-26  Miklos Szeredi <[e-mail]>

	* libfuse API change: open, read, write, flush, fsync and release
	are passed a 'struct fuse_file_info' pointer containing the open
	flags (open and release), and the file handle.  Verion changed to
	3.0.

2004-11-23  Miklos Szeredi <[e-mail]>

	* More cleanups in the kernel

	* The 10,229 charater device number has been assigned for FUSE

	* Version file checking fix (reported by Christian Magnusson)

	* fusermount: opening the fuse device now doesn't need /sys.

	* Optimize reading by controlling the maximum readahead based on
	the 'max_read' mount option

	* fixes for UCLIBC (Christian Magnusson)

2004-11-19  Miklos Szeredi <[e-mail]>

	* Cleaned up kernel in preparation for merge into mainline:

	* Use /sys/fs/fuse/version instead of /proc/fs/fuse/version

	* Use real device (/dev/fuse) instead of /proc/fs/fuse/dev

	* __user annotations for sparse

	* allocate individual pages instead of kmalloc in fuse_readdir,
	fuse_read and fuse_write.

	* Fix NFS export in case "use_ino" mount option is given

	* Make libfuse and fusermount compatible with future versions

	* fusermount: properly add mount options to /etc/mtab

2004-11-15  Miklos Szeredi <[e-mail]>

	* fusermount: do not resolve last component of mountpoint on if it
	is '.' or '..'.  This new path resolvation is now done on mount as
	well as unmount.  This enables relative paths to work on unmount.

	* fusermount: parse common mount options like "ro", "rw", etc...

	* Allow module params to be changed through sysfs

2004-11-14  Miklos Szeredi <[e-mail]>

	* Released 2.1-pre1

2004-11-14  Miklos Szeredi <[e-mail]>

	* Fix bug in fuse_readpages() causing Oops in certain situations.
	Bug found by Vincenzo Ciancia.

	* Fix compilation with kernels versions > 2.6.9.

2004-11-11  Miklos Szeredi <[e-mail]>

	* Check kernel interface version in fusermount to prevent
	strangeness in case of mismatch.

	* No need to allocate fuse_conn until actual mount happens

	* Fix potential race between umount and fuse_invalidate

	* Check superblock of proc file in addition to inode number

	* Fix race between request_send_noreply() and fuse_dev_release()

2004-11-10  Miklos Szeredi <[e-mail]>

	* Separate configure for the kernel directory

	* Don't allow write to return more than 'count'

	* Extend kernel interface for future use

2004-11-09  Miklos Szeredi <[e-mail]>

	* Fix 'makeconf.sh' to use autoreconf if available

2004-11-08  Miklos Szeredi <[e-mail]>

	* Add ino argument to 'fuse_dirfil_t'.  NOTE: This breaks source
	compatibility with earlier versions.  To compile earier versions
	just add '-DFUSE_DIRFIL_COMPAT' compile flag or fix the source.
	Do not use the "use_ino" mount flag with filesystems compiled with
	FUSE_DIRFIL_COMPAT.

	* Add pkg-config support.  To compile a FUSE based filesystem you
	can do  "gcc -Wall `pkg-config --cflags --libs fuse` myfs.c -o myfs"
	or similar.  Note, that the PKG_CONFIG_PATH environment variable
	usually needs to be set to "/usr/local/lib/pkgconfig".

	* fuse.h is now installed in ${prefix}/include/fuse/

2004-11-02  Miklos Szeredi <[e-mail]>

	* Added "use_ino" mount option.  This enables the filesystems to
	set the st_ino field on files

2004-11-01  Miklos Szeredi <[e-mail]>

	* Fix compile problems with ancient (<=2.4.18) kernels (reported
	by Jeremy Smith)

	* Add "allow_root" mount option.  Patch by Yaroslav Rastrigin

	* Clear the 'exited' flag when mail loop is finished

2004-10-28  Miklos Szeredi <[e-mail]>

	* Make xattr functions work under 2.6 (bug found by Vincenzo
	Ciancia)

2004-10-26  Miklos Szeredi <[e-mail]>

	* Reset request in fuse_flush() (bugreport by David Shaw)

2004-10-21  Miklos Szeredi <[e-mail]>

	* fuse_main() now does not exit on error, rather it returns an
	error code

	* Exported __fuse_setup() and __fuse_teardown() functions, which
	make it easier to implement a custom event loop.

	* Use daemon() call to background the filesystem after mounting.
	This function closes the standard input, output and error and
	changes the current working directory to "/".

2004-10-14  Miklos Szeredi <[e-mail]>

	* Released 1.9

2004-10-09  Miklos Szeredi <[e-mail]>

	* Don't allow fuse_flush() to be interrupted (bug found by David
	Shaw)

2004-09-27  Miklos Szeredi <[e-mail]>

	* Add PID to fuse_context.  Patch by Steven James

	* Change file handle type to 'unsigned long' in kernel interface

2004-09-22  Miklos Szeredi <[e-mail]>

	* A slight API change: fuse_get_context() doesn't need the "fuse"
	pointer, but the returned context contains it instead.  The
	fuse_get() function is not needed anymore, so it's removed.

	* Fix mounting and umounting FUSE filesystem under another FUSE
	filesystem by non-root (bug spotted by Valient Gough)

2004-09-21  Miklos Szeredi <[e-mail]>

	* Fix deadlock in case of memory allocation failure.  Patch by
	Christian Magnusson

2004-09-16  Miklos Szeredi <[e-mail]>

	* Check memory allocation failures in libfuse

2004-09-14  Miklos Szeredi <[e-mail]>

	* Check temporary file creation failure in do_getdir().  Bug
	spotted by Terje Oseberg

2004-09-13  Miklos Szeredi <[e-mail]>

	* Allow "large_read" option for 2.6 kernels but warn of deprecation

	* Make requests non-interruptible so race with FORGET is avoided.
	This is only a temporary solution

	* Support compiling FUSE kernel module on 2.4.x UML kernels

2004-09-09  Miklos Szeredi <[e-mail]>

	* Fix bug in case two FORGETs for the same node are executed in
	the wrong order.  Bug spotted and endured for months by Franco
	Broi, and logfile for solution provided by Terje Oseberg

2004-09-01  Miklos Szeredi <[e-mail]>

	* Add -D_REENTRANT to the compile flags

	* Add documentation of fuse internals by Terje Oseberg

2004-08-16  Miklos Szeredi <[e-mail]>

	* Change release method to be non-interruptible.  Fixes bug
	causing missing release() call when program which has
