ChangeLog, bitops.h:
bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap): Change to
return the previous state of the bit that is being marked or unmarked.
For speed optimization.
ChangeLog, pass3.c:
pass3.c (check_directory): Only do the loop detection algorithm if
we've searched over 2048 parent directories and haven't found the end
yet. This means that in the common case, we don't allocate or clear
the inode_loop_detection bitmap, which for large systems, merely
clearing the bitmap for each directory was turning out to be quite
expensive. Thanks to Jani Jaakkola (jjaakkol@cs.helsinki.fi) for
identifying this problem.
ChangeLog, Makefile.in, e2fsck.h, unix.c:
Makefile.in: Call sync after finishing building all in this directory.
unix.c (PRS): sync the filesystem before trying to use BLKFLSBUF, to
minimize the chance of causing dirty blocks to get dropped.
e2fsck.h: Manually define BLKFLSBUF if not defined, and we're on a
Linux/i386 system.
