* Release of E2fsprogs 1.26
2002-02-03 Theodore Tso <tytso@valinux.com>
* mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
so that the number of directories in use is adjusted
appropriately.
* alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
which optionally will modify the number of directories
count.
2002-01-03 Theodore Tso <tytso@mit.edu>
* dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
