	* Fix API version 21 and 22 compatibility for fuse_teardown.
	Reported by Bgs

2006-11-29  Miklos Szeredi <[e-mail]>

	* fusermount: Print a more helpful message in case the kernel
	doesn't support the 'fuseblk' filesystem type.  This has been
	biting ntfs-3g users.  Reported by Yura Pakhuchiy

	* kernel: fix build problem for "make -C ...".  Reported by
	Stephen Bryant

2006-11-19  Miklos Szeredi <[e-mail]>

	* Fix bug in certain error paths of lookup routines.  The request
	object was reused for sending FORGET, which is illegal.  This bug
	could cause an Oops in linux-2.6.18 or in fuse-2.6.0, and might
	silently corrupt memory in earlier versions.  Report and test
	program by Russ Cox

2006-11-11  Miklos Szeredi <[e-mail]>

	* Print an error if an incompatible kernel interface version is
	detected in INIT.  This will only show if filesystem is started
	with -d or -f

	* Fix order of fuse_destroy()/fuse_unmount() in error cleanup of
	fuse_setup_common().  Reported by Szakacsits Szabolcs

2006-11-06  Miklos Szeredi <[e-mail]>

	* Fix automake problem.  Patch from Nix

2006-10-26  Miklos Szeredi <[e-mail]>

	* Fix mount.fuse to use /bin/sh instead of /bin/bash, which is not
	always available on embedded systems.  Patch from Paul Smith

	* Fix util/Makefile.am, so that failure to run update-rc.d or
	device creation doesn't cause make to fail.  Reported by Paul
	Smith

2006-10-21  Miklos Szeredi <[e-mail]>

	* Released 2.6.0

2006-10-18  Miklos Szeredi <[e-mail]>

	* fusermount: don't try to create a lock file if /etc/mtab is a
	symlink.  Report and patch from Alexei Sheplyakov (debian bug
	#393693)

2006-10-17  Miklos Szeredi <[e-mail]>

	* Minor changes, sync with mainline tree

2006-10-16  Miklos Szeredi <[e-mail]>

	* Released 2.6.0-rc3

2006-10-15  Miklos Szeredi <[e-mail]>

	* kernel: cleanups

2006-10-13  Miklos Szeredi <[e-mail]>

	* kernel: Fix compilation on patched 2.6.18 (fc6) and 2.6.19.
	Report from David Shaw

	* lib: Fix lost error on renaming a file. Report from David Shaw

	* lib: Fix lost error on hiding open files (renaming to
	.fuse_hiddenXXXX)

	* kernel: Fix a rare hang on SMP/32bit on heavy filesystem
	activity.  The cause of the bug was that some calls to
	i_size_write() were not protected by a lock, and hence
	i_size_seqcount could become corrupted.  This caused subsequent
	calls to i_size_read() to spin forever.  This is a long standing
	bug was probably introduced in version 2.2, and thought to be
	related to NFS exporting (it's not).  It was reported by various
	people, but Dana Henriksen has finally helped me to track it down,
	so big thanks to him

	* kernel: Protect against truncation of a swapfile

2006-10-10  Miklos Szeredi <[e-mail]>

	* kernel: Check for signature of super_operations->umount_begin().
	Ubuntu kernel 2.6.17 seems to use the new signature found in
	2.6.18.  Thanks to Florent Mertens for the report

2006-10-08  Miklos Szeredi <[e-mail]>

	* Make sure inode numers wrap around at 2^32.  This is needed on
	dual 64bit/32bit architectures, because 32bit applications using
	the non-largefile interface would otherwise break (EOVERFLOW error
	would be returned by the stat() system call family)

	* ulockmgr: handle the case, when a locking operation fails
	because no more file desctriptors are available in
	ulockmgr_server.  Also work around a Linux kernel bug (known to
	exist for all Linux kernel versions <= 2.6.18) which may cause
	sent file descriptors to be lost in the above case

	* ulockmgr: optimize file descriptor use

	* restore needed cpp flags to util/Makefile.am

	* Install udev rules as 99-fuse.rules instead of 60-fuse.rules

	* Minor clean up of udev rules

	* Add a synchronous DESTROY message to kernel interface.  This is
	invoked from umount, when the final instance of the filesystem is
	released.  It is only sent for filesystems mounted with the
	'blkdev' option for security reasons.

	* If the DESTROY message is received, call the filesystem's
	->destroy() method.  In this case it's not called from session
	destruction as it would be otherwise.

2006-10-01  Miklos Szeredi <[e-mail]>

	* Released 2.6.0-rc2

2006-10-01  Miklos Szeredi <[e-mail]>

	* Add support for FLUSH+RELEASE operation for FreeBSD.  Original
	patch by Csaba Henk

	* Add init script to insert fuse module and mount the control
	filesystem.  The script is installed as /etc/init.d/fuse and on
	debian based systems (where update-rc.d is available) symlinks
	from /etc/rc*.d/ are also installed.

	* Include '#define FUSE_USE_VERSION=XX' into examples so they
	become more self contained.

2006-09-30  Miklos Szeredi <[e-mail]>

	* API changes:

	* Move lock_owner from a separate argument into fuse_file_info

	* Add a flag to fuse_file_info indicating (1) a highlevel lock
	operation (unlock all) was initiated by a flush, (2) a lowlevel
	release operation should perform a flush as well.

	* fusermount: revert modprobe change (2006-08-18) since it
	doesn't work reliably with udev

	* Add support for block device backed filesystems.  This mode is
	selected with the 'blkdev' option, which is privileged.

	* Add support for the bmap (FIBMAP ioctl) operation on block
	device backed filesystems.  This allows swapon and lilo to work on
	such filesystems.

	* kernel changes:

	* Drop support for kernels earlier than 2.6.9.  Kernel module from
	previous (2.5.x) release can be used with library from this
	release

	* In fuse_dentry_revalidate() use dget_parent() instead of
	dereferencing d_parent, since there's no protection against parent
	changing and going away

	* Protect nlookup from concurrent updates

	* In lookup if a directory alias exists but is unused,
	then get rid of it, otherwise return -EBUSY.

	* In mkdir if a directory alias exists, return success, but leave
	dentry negative.  In reality this could happen if a remote rename
	immediately followed the mkdir.

	* Don't BUG in fuse_iget() if multiple retries are needed to get a
	good inode.  This could happen if several lookups are racing for
	the same inode.

2006-09-29  Miklos Szeredi <[e-mail]>

	* Fix compilation on 2.6.9.  Report from Troy Ayers

2006-09-27  Miklos Szeredi <[e-mail]>

	* Fix Oops in fuse_readpages().  Reported by David Shaw

2006-09-24  Csaba Henk <[e-mail]>

	* Add support for nanosec times on FreeBSD

	* Fix FreeBSD compatibility issues

2006-09-23  Miklos Szeredi <[e-mail]>

	* Fix one more compatibility bug.  Thanks to Ricardo Correia

	* Fix utimens compilation with uClibc.  Patch from Jamie Guinan

2006-09-22  Miklos Szeredi <[e-mail]>

	* Fixed several compatibility bugs in low level interface.
	Reported by Ricardo Correia

	* Add workaround for ARM caching bug

2006-09-16  Miklos Szeredi <[e-mail]>

	* Rename new utimes() method to more logical utimens()

2006-09-14  Miklos Szeredi <[e-mail]>

	* Fuse tried to unlink already unlinked hidden files.  Bug
	reported by Milan Svoboda

2006-09-10  Miklos Szeredi <[e-mail]>

	* Released 2.6.0-rc1

2006-09-10  Miklos Szeredi <[e-mail]>

	* kernel: Fix unlock on close for kernels < 2.6.18

	* Add ulockmgr library & server.  This can be used for handling
	file locking requests either directly from libfuse or over a
	network, etc.  This first version is not optimized and the number
	of file descriptors it uses may get out of hand

2006-09-07  Miklos Szeredi <[e-mail]>

	* lib: Add interrupt support to high level library, which may be
	enabled with the 'intr' mount option.

	* When an operation is interrupted the thread handling that
	operation will receive SIGUSR1 (or other signal specified with the
	'intr_signal=N' option).  The library installs a no-op signal
	handler for this signal, unless there's already a handler
	installed.

	* The filesystem may query interrupt status (regardless of 'intr')
	with the fuse_interrupted() function.

	* mount.fuse: initialize $HOME if not set.  Report from Sven Goldt

2006-09-03  Miklos Szeredi <[e-mail]>

	* lib: Multithreaded loop now allows unlimited number of threads.
	This is needed for locking operations which may block
	indefinitely.  Also the kernel now doesn't limit the number of
	outstanding requests so the library shouldn't do so either.

2006-09-01  Miklos Szeredi <[e-mail]>

	* Fix recursive lock bug in interrupt handling

	* Add utimes() method to highlevel interface, which supports
	setting times with nanosecond resolution

2006-08-18  Miklos Szeredi <[e-mail]>

	* kernel: fix page leak if fuse_readpages() failed in it's
	initialization.  Bug found and original patch from Alexander
	Zarochentsev

	* For linux kernels >=2.6.18 (2.6.19 if using the fuse module from
	the kernel tree) the statfs method will receive the path within
	the filesystem on which the stat(v)fs syscall was called

	* fusermount: try to modprobe fuse module if invoked by root and
	unable to open device.  This is needed with udev, since the device
	node will be created only when the module is inserted, hence
	module autoloading won't work.  Reported by Szakacsits Szabolcs

2006-07-30  Miklos Szeredi <[e-mail]>

	* fusermount: if selinux is active, restore the original file's
	security context in unmount_rename().  Redhat bugzilla id 188561.
	Patch from Yves Perrenoud

	* Add POSIX file locking operation to high level library

	* Initialize context for unlink of hidden files on umount.  Bug
	reported by Tim Stoakes

2006-07-14  Miklos Szeredi <[e-mail]>

	* Multiple release() calls can race with each other, resulting in
	the hidden file being deleted before the last release finishes.
