+Subject: ext4: fix bigalloc regression
+
+From: Eric Whitney <enwlinux@gmail.com>
+
+commit d0abafac8c9162f39c4f6b2f8141b772a09b3770 upstream.
+
+Commit f5a44db5d2 introduced a regression on filesystems created with
+the bigalloc feature (cluster size > blocksize).  It causes xfstests
+generic/006 and /013 to fail with an unexpected JBD2 failure and
+transaction abort that leaves the test file system in a read only state.
+Other xfstests run on bigalloc file systems are likely to fail as well.
+
+The cause is the accidental use of a cluster mask where a cluster
+offset was needed in ext4_ext_map_blocks().
