+# FS QA Test No. 043
+#
+# This test is motivated by an fsync issue discovered in btrfs.
+# The issue was that we could lose file data, that was previously fsync'ed
+# successfully, if we end up adding a hard link to our inode and then persist
+# the fsync log later via an fsync of other inode for example.
+#
+# The btrfs issue was fixed by the following linux kernel patch:
+#
+#  Btrfs: fix fsync data loss after adding hard link to inode
