+# DESCRIPTION:
+# Verify all cp --reflink modes work with modified file.
+#
+# STRATEGY:
+# 1. Verify "cp --reflink=never|auto|always" behaves as expected.
+# Two different modes of operation are tested.
+#
+# a. zfs_bclone_wait_dirty=0: FICLONE and FICLONERANGE fail with EINVAL
+# when there are dirty blocks which cannot be immediately cloned.
+# This is the default behavior.
+#
+# b. zfs_bclone_wait_dirty=1: FICLONE and FICLONERANGE wait for
+# dirty blocks to be written to disk allowing the clone to succeed.
+# The downside to this is it may be slow which depending on the
+# situtation may defeat the point of making a clone.
