From: Eric Sandeen Date: Mon, 31 May 2010 02:49:39 +0000 (-0400) Subject: ext4: Fixed inode allocator to correctly track a flex_bg's used_dirs X-Git-Tag: firefly_0821_release~10186^2~1328 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=84b29e4a5037d97d72da25fc40d879a29bf1846d;p=firefly-linux-kernel-4.4.55.git ext4: Fixed inode allocator to correctly track a flex_bg's used_dirs commit c4caae25187ff3f5e837c6f04eb1acc2723c72d3 upstream (as of v2.6.34-rc3) 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.
