+# Set the NOCOW attribute for directories of journal files. This flag
+# is inherited by their new files and sub-directories. Matters only
+# for btrfs filesystems.
+#
+# WARNING: Enabling the NOCOW attribute improves journal performance
+#     substantially, but also disables the btrfs checksum logic. In
+#     btrfs RAID filesystems the checksums are needed for rebuilding
+#     corrupted files. Without checksums such rebuilds are not
+#     possible.
+#
+# In a single-disk filesystem (or a filesystem without redundancy)
+# enabling the NOCOW attribute for journal files is safe, because
+# they have their own checksums and a rebuilding wouldn't be possible
+# in any case.
