The top-level COPYING file states that the e2p and ext2fs libraries
are available under the LGPLv2. The files were incorrectly labelled.
Alex Thomas/Luster has been consulted wrt to the ext3_extents.h file;
the rest of the files were primarily authored by Theodore Ts'o.

Print out the currently supported features of e2fsprogs/libext2fs
via a new "debugfs supported_features" command. This helps scripts
to know whether it is possible to try and enable specific features
in the filesystem.

This was the original name used by Lustre's patches; keep the plural
when converting feature names to a feature mask for compatibility's
sake.

Allow the old name of uninit_groups when converting feature names for
backwards compatibility for scripts running mke2fs and tune2fs.

This name is a more intuitive option when running mke2fs.

This creates a new enhanced edit_feature function for libe2p which
supports a different set of feature flags that are OK to clear as
opposed to set, and which returns more specific information about why
the user provided an invalid edit feature command.

Add FLEX_BG as a supported feature bit.
Add support to mke2fs to create filesystems with FLEX_BG.
Add support to tune2fs to add (and remove, if it won't break
filesystem consistency) the FLEX_BG feature.

Add support for printing the huge_file, gdt_checksum, dir_nlink,
extra_isize, extent, and 64bit features.

This feature is initially intended for testing purposes; it allows an
ext2/ext3 developer to create very large filesystems using sparse files
where most of the block groups are not initialized and so do not require
much disk space. Eventually it could be used as a way of speeding up
mke2fs and e2fsck for large filesystem, but that would be best done by
adding an RO_COMPAT extension to the filesystem to allow the inode table
to be lazily initialized on a per-block basis, instead of being entirely initialized
or entirely unused on a per-blockgroup basis.

Change the maximum allowable blocksize to be 65536. This allows e2fsck to
check filesystems with a pagesize of 65536, and mke2fs to accept -b 65536.
Of course such a filesystem will not currently work on a Linux/x86 system,
at least not as of this writing!
feature.c: Remove backward compatibility #ifdef's for old ext2_fs.h
header files.
.del-ext2_fs.h~7a460879, ChangeLog:
ext2_fs.h (EXT3_FEATURE_INCOMPAT_JOURNAL_DEV): Add definition for use
with external journal devices.
Makefile.in (uuid_time): Compile uuid_time in two steps (first create
.o, then link it against the libraries) to work around bug in a.out
linker.
dll/jump.funcs, dll/jump.import, dll/jump.params: Update a.out shared
library control files to reflect new added files.
ChangeLog, feature.c, jump.funcs:
feature.c: Make feature_list static; it shouldn't be exported.
dll/jump.funcs: Update a.out shared library control file.
ChangeLog, badblocks.c:
badblocks.c (flush_bufs): Use fsync() if the system doesn't support
fdatasync().
feature.c: Fix GCC warnings; add const to the char * types in the
function prototypes for e2p_feature2string and e2p_edit_feature.
ChangeLog, uuid.h, uuid_time.c:
uuid_time.c (variant_string): Declare to be static to avoid gcc warnings.
uuid.h: Add function prototypes for uuid_generate_random() and
uuid_generate_time().
ChangeLog, chattr.c:
chattr.c: Add hack to compile in a definition for S_ISLNK so we can
successfully compile even with warnings turned on.
feature.c (e2p_edit_feature), e2p.h: Add a new argument which allows
the calling application to limit what features the user is allowed to
set or clear using this function. Also add support for comma
separated lists.
Makefile.in, feature.c, e2p.h: New file which is used for displaying
and editing superblock feature sets.
ls.c (print_features, list_super): Add new function print_features
which is used to display the feature bits in the superblock.
