Change 168681 by truncs at aditya on 2009/09/19 13:50:47

	Orlov block allocator requires total no. of directories in a given file system
	as in-core superblock doesn't provide this information directly, a new variable
	called e2fs_total_dir has been added to in-memory superblock which will add the
	no. of directories in the individual groups at the time of mounting.
