Clearing SPARSE_SUPER is dangerous; it can result in a filesystem
which e2fsck can't fix easily. Since there is very few good reasons
for wanting to turn this feature off, disable tune2fs's abiity to do
this. Users who really want this can use debugfs.
Also, deprecate the tune2fs -s option. Remove it from the man page
and usage message.

Make debugfs and tune2fs reference each other in the "SEE ALSO"
section.

Previously we just let the kernel and e2fsck do this automatically,
but e2fsck will no longer automatically clear the large_file feature.
It still isn't really necessary to worry about this feature flag
explicitly, but some users seem to care.

This requires an fsck aftwards. We don't allow setting the
resize_inode feature because extensive work to tune2fs or e2fsck to
safely relocate blocks is necessary in order to reserve the blocks
needed by the resize inode.

The test_fs flag is an "ok to be used with test kernel code" flag. It
makes it easier for us to determine whether a filesystem should be
mounted using ext4 or not.

TUNE2FS_SKIP_MOUNT_CHECK is set, do not try
to check if the filesystem is mounted.
(update_feature_set): If the compatibility bitmasks were
not modified, don't set the superblock dirty bit.
caret ('^') character to negate feature sets when using
the -O option. Define the has_journal feature to avoid
confusion about what ^has_journal means.
function in get_device_by_label.c to allow the use of
UUID= or LABEL= when creating filesystems which use external
journal dev (e.g. mke2fs -J device=LABEL=<journal_label>).
tune2fs.c: Use superblock s_journal_uuid to locate an external
journal device instead of s_journal_dev when removing it.
Allow opening journal devices to set the label and UUID
in the ext2 superblock.
mke2fs.c, tune2fs.c: Free journal_device after use, as it is
malloc'd in interpret spec.
tune2fs.c, mke2fs.c, util.c, util.h (print_check_message): Move the
message which displays how often the filesystem will be checked from
mke2fs into a utility subroutine. Then cause tune2fs to call that
function to display the message after adding a journal to a
filesystem.
mke2fs.8.in: Add manual page fixups and explanation for why it's good
to check filesystems periodically from Andreas Dilger.
Clarify some of the Changelog entries.
ChangeLog, fsck.8.in, mke2fs.8.in, tune2fs.8.in:
fsck.8.in, mke2fs.8.in, tune2fs.8.in: Fix typo's and make other
clarifications suggested by Andreas Dilger.
ChangeLog, tune2fs.c:
tune2fs.c (update_feature_set): Clean up some printf messages.
dumpe2fs.c (main): Add new flag, -i, which will allow dumpe2fs to dump
out the filesystem statistics from an ext2 image file.
Many files:
e2image.8.in: New manual page
badblocks.8.in, e2label.8.in, mke2fs.8.in mklost+found.8.in,
tune2fs.8.in: Update location of e2fsprogs to be
http://e2fsprogs.sourceforge.net.
tune2fs.c (parse_tune2fs_options): Interpret -c 0 as -c -1 (for
backwards compatibility with older kernels). -c 0 makes more sense to
users.
tune2fs.8.in:
Update tune2fs manual papge so that it is up to date.
ke2fs.8.in, tune2fs.8.in: Change man paegs to document that the
journal must be bewteen 1024 and 10,240 file system blocks.
mke2fs.c, tune2fs.c: Change to use figure_journal_size()
util.c, util.h (figure_journal_size): Change journal_default_size into
routine which also converts the requested journal size into filesystem
blocks and does bounds checking to make sure the journal is sized
reasonably. Renamed function to journal_default_size.
parse_journal_opts): Remove bounds check for the journal size, since
this is now done in figure_journal_size, and based on the number of
filesystem blocks, as opposed to using the absolute size of the
journal.
tune2fs.c, mke2fs.c, tune2fs.8.in, mke2fs.8.in: Change user interface
so that -J is used to specify journal options, and -j is used to
request creation of a journal using default values. (This is a UI
change, but we haven't done a formal release, and it makes things much
more consistent with the rest of the options out there.)
tune2fs.c: Add support for removing a filesystem from an external
journal; we correctly remove the filesystem UUID from the external
journal's filesystem list.
tune2fs.c (update_feature_set, add_journal): Moved to separate
functions. Added ability to add and remove the journal while the
filesystem is live. Added support for setting a time-based UUID.
Removed zero-initialized static variables.
mke2fs.c, util.c, util.h (strcasecmp, proceed_question,
check_plausibility, parse_journal_opts, check_mount): Moved functions
to util.c so they can be used by tune2fs.
mke2fs.c (main): Change ext2fs_add_journal_fs() to
ext2fs_add_journal_inode() to reflect function renaming.
tune2fs.8.in: Update manual page to document what happens if
max_mount_count is negative.
tune2fs.c (main): Allow setting the maximal count value to be
negative, since the kernel interprets that as forcing a check.
chattr.1.in:
lsattr.1.in: Change "version" to "version/generation number".
chattr.1.in: Fix stupid file vs filesystem typo.
tune2fs.c Fix spelling error (spare vs sparse).
mke2fs.c (PRS): Add safety check to make sure the number of blocks
doesn't exceed 32 bits on a 64 bit machine.
chattr.c: Random cleanup; file-only variables are now static. Options
for setting/clearings flags put into order, and #ifdef's removed
(since we now use a built-in header file). Add error message if user
tries to set and reset the same flag.
lsattr.c: Random cleanup; file-only variables are now static. The -l
"long" listing has been changed to look nicer. Options names have
been renamed to be more descriptive.
tune2fs.c (main): Add a new option -O which allows the user to set and
clear certain "safe" filsystem feature flags. Currently, the only
ones which are supported for modification are sparse_superblock and
filetype.
mke2fs.c (PRS): Add new option -O which allows the user to request
filesystems with specific filesystem options. By default on 2.2 and
later systems, create filesystems that have both file type information
and sparse superblocks.
