+Subject: Btrfs: relocate csums properly with prealloc extents
+
+A user reported a problem where they were getting csum errors when running a
+balance and running systemd's journal. This is because systemd is awesome and
+fallocate()'s its log space and writes into it. Unfortunately we assume that
+when we read in all the csums for an extent that they are sequential starting at
+the bytenr we care about. This obviously isn't the case for prealloc extents,
+where we could have written to the middle of the prealloc extent only, which
+means the csum would be for the bytenr in the middle of our range and not the
+front of our range. Fix this by offsetting the new bytenr we are logging to
+based on the original bytenr the csum was for. With this patch I no longer see
+the csum errors I was seeing. Thanks,
+
