From: John Keeping Date: Tue, 18 Apr 2023 10:19:05 +0000 (+0100) Subject: mm: shrinkers: fix debugfs file permissions X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2124f79de6a909630d1a62b01ecc32db9f967181;p=linux.git mm: shrinkers: fix debugfs file permissions 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.
