Thanks, applied.  The commit description is not accurate (I suspect it
was obsoleted when your patch for RHEL was forward ported) do I
dropped it.

I adjusted the patch summary to be:

    ext4: add missing brelse() add_new_gdb_meta_bg()'s error path

The commments for the Fixes and Cc: stable@kernel.org also apply.
