37 # This test effectively requires xfs_io with these commits
38 # 2a42470b xfs_io: copy_file_range length is a size_t
39 # 1a05efba io: open pipes in non-blocking mode
41 # Without those commits test will hang on old kernel when copying
42 # very large size and when copying from a pipe.
44 # We require a new xfs_io feature of passing an open file as the
45 # copy source, as an indication that the test can run without hanging
46 # with large size argument and to avoid opening pipe in blocking mode.
48 # Test both basic copy_range and copy_range -f availability
