-Subject: [PATCH] ext4: fix check to prevent initializing reserved inodes
-
-Commit 8844618d8aa7: "ext4: only look at the bg_flags field if it is
-valid" will complain if block group zero does not have the
-EXT4_BG_INODE_ZEROED flag set.  Unfortunately, this is not correct,
-since a freshly created file system has this flag cleared.  It gets
-almost immediately after the file system is mounted read-write --- but
-the following somewhat unlikely sequence will end up triggering a
-false positive report of a corrupted file system:
-
-   mkfs.ext4 /dev/vdc
-   mount -o ro /dev/vdc /vdc
-   mount -o remount,rw /dev/vdc
-
-Instead, when initializing the inode table for block group zero, test
-to make sure that itable_unused count is not too large, since that is
-the case that will result in some or all of the reserved inodes
-getting cleared.
-
-This fixes the failures reported by Eric Whiteney when running
-generic/230 and generic/231 in the the nojournal test case.
-
-Fixes: 8844618d8aa7 ("ext4: only look at the bg_flags field if it is valid")
