This value generally shouldn't be smaller than
the blocksize of the filesystem, since then too many inodes will be made.
Be warned that is not possible to expand the number of inodes on a
filesystem after it is created, so be careful decided the correct
value for this parameter.

journal in MB (1024*1024 bytes). Any size between 4MB and 100MB may be used.
Use of this option implies that the journal will be stored in the
filesystem, so it must be small enough to fit into the filesystem.

ChangeLog, debugfs.8.in, debugfs.c: Add a -V option which displays the current version. ChangeLog, unix.c: unix.c (e2fsck_update_progress): Remove unused variables. ChangeLog, inode.c: inode.c (get_next_blockgroup): Fix bug where if get_next_blockgroup() is called early because of a missing inode table in a block group, the current_inode counter wasn't incremented correctly. ChangeLog, tst_uuid.c: tst_uuid.c (main): Fixed bogus declaration of the main's argv parameter. ChangeLog, test_icount.c: test_icount.c (main): Fix main() declaration so that it returns int, not void. Many files: fsck.c (ignore): Remove unused variable cp. chattr.c (fatal_error): tune2fs.c (usage): lsattr.c (usage): dumpe2fs.c (usage): badblocks.c (usage): Remove volatile from declaration. fsck.c: Change use of strdup to be string_copy, since we don't trust what glibc is doing with strdup. (Whatever it is, it isn't pretty.)

.BI \-T " fs-type"
ChangeLog, fsck.8.in, fsck.c, fsck.h, mke2fs.8.in, mke2fs.c: * mke2fs.c (PRS, set_fs_defaults): Add new option -T which allows the user to specify the how the filesystem is to be used. Mke2fs now chooses the filesystem parameters automatically based on the size of the filesystem and the intended use of the filesystem. Add new option -n which simply goes through the calculations to determine the parameters of the filesystem the system would make. * fsck.c, fsck.h: Add support for new option -C. This option will automatically manage e2fsck processes so that they will print completion/progress bars. If multiple filesystems are being checked, arrange to make sure that only one e2fsck process is displaying a progress bar at a time.

Specify how the filesystem is going to be used, so that mke2fs can
automatically determine the optimal filesystem parameters. The only
filesystem type which is currently supported is "news".

Many files: e2label.c: Fix -Wall warning by making functions static. chattr.1.in: Document that the append-only attribute may only be set or cleared by the superuser. Update all manual pages to that the availability section is up-to-date. e2label.8.in, tune2fs.8.in: Update manual page to state that labels must be no longer than 16 characters, or they will be truncated. e2label.c (change_label), tune2fs.c (main): If the label is longer than 16 characters, print a warning message stating that the label will be truncated. mke2fs.c (PRS): If the user specifies a filesystem size, and it's larger than the apparent size of the device, print a warning message and ask if the user wants to proceed.

Bug and suggested fix by Pavel Machek <pavel@bug.ucw.cz> ChangeLog, swapfs.c: swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3 kernels that use i_generation instead of i_version. Patch supplied by Jon Bright <sircus@sircus.demon.co.uk>. ChangeLog, mke2fs.8.in: mke2fs.8.in: Fix typo in man page which caused the badblocks command to not show up in the "SEE ALSO" section. ChangeLog, expect.1, expect.2, image.gz, name: f_recnect_bad: New test which checks the case where a disconnect inode also bad inode fields; we need to make sure e2fsck offers to fix the inode (or clear the inode, as necessary).
