+Subject: ext4: enable the lazy init thread when remounting read/write
+
+From: Theodore Ts'o <tytso@mit.edu>
+
+commit eb1f822c76beeaa76ab8b6737ab9dc9f9798408c upstream.
+
+In commit a44be64bbecb ("ext4: don't clear SB_RDONLY when remounting
+r/w until quota is re-enabled") we defer clearing tyhe SB_RDONLY flag
+in struct super.  However, we didn't defer when we checked sb_rdonly()
+to determine the lazy itable init thread should be enabled, with the
+next result that the lazy inode table initialization would not be
+properly started.  This can cause generic/231 to fail in ext4's
+nojournal mode.
+
+Fix this by moving when we decide to start or stop the lazy itable
+init thread to after we clear the SB_RDONLY flag when we are
+remounting the file system read/write.
+
+Fixes a44be64bbecb ("ext4: don't clear SB_RDONLY when remounting r/w until...")
