+# FS QA Test 161
+#
+# Test to make sure that RAID1 write hole reads good data.
+# To see the failure use the following mount options.
+#   -o max_inline=0,nodatasum
+#   or
+#   -o max_inline=0,nodatacow
+#  and needs ML kernel patch so that we can avoid the arbitary
+#  disk to be used to read the mirror (which is based on the PID).
+#
+#  btrfs: add mount option read_mirror_policy
+#  btrfs: add read_mirror_policy parameter devid
+#  btrfs: read_mirror_policy ability to reset
