ChangeLog, mke2fs.c, tune2fs.8.in:
tune2fs.8.in: Fix minor display bug in the nroff.
mke2fs.c (show_stats, write_inode_tables): Use the log10 function to
calculate the display of block numbers so that things look nice on an
80 character display.
mke2fs.c (usage): Add the sparse-super-flag to the usage message.
ChangeLog, e2fsck.c, pass1.c, pass2.c, problem.c, problem.h, unix.c:
unix.c (main): Move ext2fs_close() after e2fsck_free_context() since
e2fsck_free_context may reference data in ctx->fs.
e2fsck.c (e2fsck_reset_context): Make sure ctx->fs is non-NULL before
checking ctx->fs->dblist.
pass1.c (e2fsck_pass1): Use the device check subroutine on FIFO's and
Socket's, so that we catch bogus immutable inodes.
pass2.c (process_bad_inode): Process bad socket and fifo's.
problem.h, problem.c: Define new problem codes PR_2_BAD_FIFO and
PR_2_BAD_SOCKET.
