+Subject: xfs: fix reading of wrapped log data
+
+From: Dave Chinner <dchinner@redhat.com>
+
+commit 6ce377afd1755eae5c93410ca9a1121dfead7b87 upstream.
+
+Commit 4439647 ("xfs: reset buffer pointers before freeing them") in
+3.0-rc1 introduced a regression when recovering log buffers that
+wrapped around the end of log. The second part of the log buffer at
+the start of the physical log was being read into the header buffer
+rather than the data buffer, and hence recovery was seeing garbage
+in the data buffer when it got to the region of the log buffer that
+was incorrectly read.
