dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
which will return deleted directory entries.
ext2fs_dir_iterate2 takes a new callback function which
is identical with the one used by
ext2fs_dblist_dir_iterate(). If the directory entry is
deleted, the callback function will be called with the
entry paraemter set to DIRENT_DELETED_FILE.
Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
ext2fs_block_alloc_stats): New functions which update
block/inode allocation statistics in the bitmaps, block
group descriptors, and superblock.
mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
expanddir.c (expand_dir_proc), bb_inode.c
(clear_bad_block_proc, set_bad_block_proc,
ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
Update to use new block/inode allocation statistics.
