+Subject: ext4: fix fencepost in s_first_meta_bg validation
+
+From: Theodore Ts'o <tytso@mit.edu>
+
+commit 2ba3e6e8afc9b6188b471f27cf2b5e3cf34e7af2 upstream.
+
+It is OK for s_first_meta_bg to be equal to the number of block group
+descriptor blocks.  (It rarely happens, but it shouldn't cause any
+problems.)
