| Subject: mm: shrinkers: fix debugfs file permissions |
| Date: Tue, 18 Apr 2023 11:19:05 +0100 |
| |
| The permissions for the files here are swapped as "count" is read-only and |
| "scan" is write-only. While this doesn't really matter as these |
| permissions don't stop the files being opened for reading/writing as |
| appropriate, they are shown by "ls -l" and are confusing. |
