ext4: Fixed inode allocator to correctly track a flex_bg's used_dirs
Eric Sandeen [Wed, 24 Mar 2010 01:32:00 +0000 (21:32 -0400)]
When used_dirs was introduced for the flex_groups struct, it looks
like the accounting was not put into place properly, in some places
manipulating free_inodes rather than used_dirs.
