Hi Anna, I recently looked into allowing sys_copy_file_range to use the clone_file_range operation so that file systems don't have to support two methods if they only support clone-like features, and one thing I noticed is that unlike for clone there are no tests for clone_file_range in xfstests, and I couldn't find a testsuite anywhere else either. Do you have any good tests available to verify the implementation? -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
