22 | # Description: | |
23 | # Verify that nopwrite still updates file metadata correctly | |
24 | # | |
25 | # Strategy: | |
26 | # 1. Create a clone with nopwrite enabled. | |
27 | # 2. Write to the file in that clone and verify the mtime and ctime change, | |
28 | # but the atime does not. | |
29 | # | |
