        * src/jffs3.c: Merge jffs3_write_super() and jffs3_put_super() into
        the routines from which they were called, put jffs3_read_super()
        in as a static function with a view to doing same RSN.
        * src/jffs3port.h: Remove prototypes of functions that died.
        * cdl/jffs3.cdl: Remove super-ecos.c
        * src/dir-ecos.c src/write.c: Increase highest_version _before_

2002-01-27  David Woodhouse  <[e-mail]>

        * src/read.c (jffs3_read_inode_range): Deal correctly with
        non-page-aligned read requests. We have to deal with the 
        case where we want to read from somewhere other than the
        beginning of a frag. 
        * src/jffs3.c (jffs3_fo_read): Use jffs3_read_inode_range
        instead of jffs3_readpage.

2002-01-25  Jonathan Larmour  <[e-mail]>

        * cdl/jffs3.cdl: We want CYGPKG_IO_FILEIO_INODE.
        * src/dir-ecos.c (jffs3_symlink): Remove. eCos doesn't support symlinks.
        (jffs3_mknod): Similar.
        (jffs3_mkdir): Don't call d_instantiate - its a nop.
        (jffs3_rename): Ditto.
        * src/file-ecos.c (jffs3_commit_write): Don't set blocks.
        * src/jffs3.c (jffs3_flash_writev): Rewrite to only write aligned
        quantities to flash.
        * src/jffs3port.h: Lots of decrufting.
        * src/os-ecos.h: Ditto (a bit).
        * src/readinode.c (jffs3_read_inode): Don't set blocks/blksize in inode.
        * src/write.c (jffs3_new_inode): Ditto when __ECOS.
        (jffs3_write_dnode): don't call writev with extra vectors
        unnecessarily.
        * src/super-ecos.c (jffs3_statfs): Remove - unused.

2002-01-25  David Woodhouse  <[e-mail]>

        * src/super-ecos.c: Cruftectomy.
        * src/compr*.[ch] src/pushpull.h: Namespace cleanups merged from
        mainstream sources. Bit push functions made inline.
        * src/pushpull.c: Removed.
        * cdl/jffs3.c: Remove reference to pushpull.c
        * src/file-ecos.c: Cruftectomy. Lots of unused stuff here.
        * src/jffs3.c src/jffs3port.h: Remove some functions from jffs3.c
        which are no longer used, move some others to jffs3port.h as
        inline functions so they don't pollute the namespace.

2002-01-24  Jonathan Larmour  <[e-mail]>

        * tests/fileio1.c: Check in listdir that the number of dirents is
        correct, taking into account existing files in case it's live.

        * src/dir-ecos.c (jffs3_readdir): move to....

        * src/jffs3.c (jffs3_fo_dirread): here. And fix the return code
        in the process so it now works.
        (filldir): Make inline and simpler.
        * src/jffs3port.h: remove filldir related stuff.

2002-01-24  David Woodhouse  <[e-mail]>

        * src/dir-ecos.c: Cruftectomy. Remove most of the stuff that was
        commented out. Remove jffs3_do_{create,link,unlink} to write.c
        * src/write.c: Add jffs3_do_{create,link,unlink} as in mainline.
        * src/nodelist.h: Prototypes for the above.
        * src/jffs3port.h: Don't include <pkgconf/kernel.h>. 
        
2002-01-23  Jonathan Larmour  <[e-mail]>

        * src/jffs3.c (jffs3_mount): Allow multiple FSs, and integration
        with flash block device.
        (jffs3_flash_read): Use flash block device.
        (jffs3_flash_erase): Ditto.
        (jffs3_flash_write): Ditto.
        (do_flash_init): Remove - now done by block device layer
        * src/list.h: Remove and reimplement from scratch to avoid GPL.
        * src/os-ecos.h: Keep flash block dev handle in superblock.
        eCos does support obsoleting as it isn't NAND only.
        * src/dir-ecos.c (jffs3_readdir): Return correct value on success.
        Merge in changes mutatis mutandis from between v1.49 and v1.51 of
        dir.c in main repository.
        * cdl/jffs3.cdl: CYGPKG_MEMALLOC more accurately CYGINT_ISO_MALLOC.
        Only jffs3.c needs to be in libextras.a
        Requires Flash block devices as an alternative for hardcoding
        the sector size, flash size and base address.
        * src/super-ecos.c (jffs3_read_super): Use flash block device for
        sector and flash sizes.
        * tests/fileio1.c: mount using block device (defined by CDL).
        No need to init here - done by flash block device layer.
        
2002-01-21  David Woodhouse  <[e-mail]>

        * src/read.c: Obtain inode lock around reading symlink target.
        * src/dir-ecos.c: Fix the long-standing up() without down() in
        jffs3_readdir() when only the '.' and '..' entries are read, from
        v1.52 of master dir.c. Merge copyright date change from v1.50 - note
        that the portability cleanups from v1.51 aren't yet merged.
        * src/os-ecos.h: Add jffs3_can_mark_obsolete() and the macros
        for getting at generic inode fields from a struct jffs3_inode_info*
        * src/nodemgmt.c: Remove an #ifndef __ECOS and use 
        jffs3_can_mark_obsolete() instead.
        * src/jffs3port.h: up() is cyg_drv_mutex_unlock() not _release()
        * src/gc.c: Merge portability cleanups - get rid of a lot of
        references to 'struct inode'. Also include the attempt at NAND
        support in jffs3_garbage_collect_deletion_dirent().
        
2002-01-11  David Woodhouse  <[e-mail]>

        * src/jffs3port.h: Switch semaphore emulation to cyg_drv_mutex_t,
        remove some kernel includes which seem gratuitous.
        * cdl/jffs3.cdl: Require CYGPKG_MEMALLOC
        * src/compr_zlib.c src/compr.c: Merge changes from mainline code
        to make mkfs.jffs3 compile again.
        
2002-01-10  David Woodhouse  <[e-mail]>

        * src/jffs3.c: The 'mode' arg passed to jffs3_open() shouldn't
        have been called 'mode'. It's 'oflags'. You have to make up a 
        mode for the newly-created file yourself.
        * src/nodelist.h src/read.c: Fix jffs3_getlink() so it takes
        portable arguments, not a dentry. Move it to read.c and symlink.c
        becomes obsolete.
        * src/symlink-ecos.c: Removed.
        * cdl/jffs3.cdl: Remove symlink-ecos.c

2002-01-09  David Woodhouse  <[e-mail]>

        * Import updated JFFS3 sources into eCos tree.

2000-08-28  Dominic Ostrowski ([e-mail])

        * started on port of JFFS3 using ramfs as a template
