Disambiguate the use of "-F" (force) flag for mke2fs to avoid dangerous
situations. The use of -F is needed for regular backing files and
for filesystems on whole block devices. It should NOT be confused
with mke2fs on an apparently-mounted or in-use filesystem.

This patch allows "inode_size" to be specified in the mke2fs.conf file,
and always compiles in the "-I" option. In addition, it disallows
specifying the inode size on rev 0 filesystems, though I don't think
this was much of a danger anyways.

The exlcusive device safety check that was added inadvertently broke
e2fsck -cc and mke2fs -cc since e2fsck and mke2fs hold the device
in exclusive access when badblocks is run. So we add a private option
to badblocks, -X, which is passed by e2fsck and mke2fs to badblocks
to indicate that it is OK to skip the EXT2_MF_BUSY checks.

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.

ext2fs_create_resize_inode() unconditionally, and depending on

superblock features are set.
mke2fs.c (create_journal_dev): Call ext2fs_create_journal_superblock()
first, so if it's going to error out, the user finds out before
waiting for the entire device to get zero'ed.
ChangeLog, util.c:
util.c (parse_journal_opts): Remove code which allowed a bare number
to be treated as a journal size.
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.
mke2fs.c (main): Flush out the "creating journal" message. Also
handle the case where the default journal size returns zero blocks ==
no journal. Print out how often the filesystem will be checked.
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: Changed the external journal code so that it simply adds a
filesystem to a journal; the journal must have bene created via
"mke2fs -O journal_dev /dev/XXX".
mke2fs.c: Add support for creating an external journal device by using
the command "mke2fs -O journal_dev /dev/XXX". Also changed the
external journal code so -j device=/dev/XXX it simply adds a
filesystem to that journal; the journal must have been created via
separate step.
dumpe2fs.c (print_journal_information): Add support for dumping
information about an external journal device.
mke2fs.c: Add new filesystem types, largefile and largefile4, for
those filesystems whose average inode size is 1MB and 4MB,
respectively. Allow the inode ratio specified to be has high as 4MB.
Make the s_max_mount_count vary between 20 and 40, to avoid needing to
check all of the filesystems at the same time. Add some random jitter
to the s_max_mount_count value so that we avoid checking all of the
filesystems at the same time when we reboot.
e2image.c, mke2fs.c, mklost+found.c, tune2fs.c, util.c, uuidgen.c: Fix
gcc -Wall complaints, including one bug in tune2fs caused by a block
automatic shadowing version of the variable we really wanted to use,
which broke the logic testing to see if the filesystem was mounted.
ChangeLog, MCONFIG.in:
(gcc-wall-new): Added new target which forgoes the make clean so we
only check the newly modified .c files.
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.
mke2fs.c (main, parse_journal_opts): Add support for creating V1
superblocks. We now pass in a journal_flags field to the journal
creation routines for this purpose.
mke2fs.c: Remove zero initializers to save a few bytes from the
executable image. (Are we excited yet?)
mke2fs.c(main): Expand the -j option so that it parses option=argument
style options, and add support for creating filesystems with external
journals.
mke2fs.8.in: Document new syntax for the -j option.
mke2fs.c (PRS): Applied Andreas Dilger's patch to make the -r -s
handling a bit more sane. (Even though -s is deprecated at this
point.)

f_journal: Update to take into account new printing by the e2fsck
program.
version.h:

mke2fs.c (zap_sector): Fix error message printed when zap_sector
fails.
dumpe2fs.c (list_desc): Fixed format string bug when printing the
inode table location in non-hex format.
dumpe2fs.c (usage): add fhx options to usage message, add -x option to
print out the per-group block numbers in hex, add line for location of
primary/backup superblock and group descriptors
mke2fs.c: rename max to group_blk_max avoid potential macro conflict
mke2fs.c (zap_sector): Change zap_bootsect to more general zap_sect.
(main): Clear the superblock when starting mke2fs, to avoid leaving
the filesystem in an inconsistent state.
mke2fs.c (PRS): Add a much more specific error message if the
filesystem size is defaulted and get_device_size returns a size of
zero. Otherwise, users get a confusing "invalid argument while passed
to ext2 library" error message.
problem.c, problem.h (PR_0_HURD_CLEAR_FILETYPE): Add new problem code.
super.c (check_super_block): If the OS type in the superblock is the
Hurd, check to see if the filetype feature is set, and offer to clear
it if so. This needs to be done since the Hurd doesn't properly
support the filetype feature. (And since the hurd allows the
transmogrification of files to special files and vice versa --- for no
good reason that I can understand --- it can't support the filetype
feature for the forseeable future, either.)
ChangeLog, mke2fs.c:
mke2fs.c (main): We forcibly turn off the filetype feature if the OS
is the hurd, since the hurd doesn't support it. (And since the hurd
allows the transmogrification of files to special files and vice versa
--- for no good reason that I can understand --- it can't support the
filetype feature for the forseeable future, either.)
mke2fs.c (proceed_question): Fix reversed sense of proceed_question
that was busted due to the internationalization patch. Fixed bug
where if proceed_question was called twice, the input buffer wasn't
cleared of the previous question's newline.
ChangeLog, expect.1, expect.2, image.gz, name:
f_hurd: Add test for Hurd-specific features (right now, just checks to
make sure the filetype feature is cleared)
ChangeLog, ls.c:
ls.c (list_super): Change the string displayed for the Hurd to be
GNU/Hurd, instead of just "GNU".
badblocks.c, dumpe2fs.c, e2label.c, mke2fs.c, tune2fs.c, uuidgen.c:
For platforms that don't define optarg.h, manually define optarg and
optind.

optarg and optind.
ChangeLog, unix.c:

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.
fsck.c (interpret_device): If there was an attempt to interpret a
device specification of the type "UUID=" or "LABEL=", and it fails,
check to see if /proc/partitions is readable. If not, print a warning
message about /proc perhaps not being mounted, and exit.
mke2fs.c (check_plausibility): Remove unneeded #include of linux/fs.h.
Add #define of MAJOR if necessary.
partinfo.c: Remove unneeded #include of linux/fs.h
