The branch stable/13 has been updated by mjg: URL: https://cgit.FreeBSD.org/src/commit/?id=1dca3a9406f12168919bdcafdb45cbbb613e9c8c commit 1dca3a9406f12168919bdcafdb45cbbb613e9c8c Author: Mateusz Guzik <mjg@FreeBSD.org> AuthorDate: 2023-09-23 00:08:49 +0000 Commit: Mateusz Guzik <mjg@FreeBSD.org> CommitDate: 2023-10-13 23:48:12 +0000 vfs cache: retire dothits and dotdothits counters They demonstrate nothing, and in case of dotdot they are not even hits. This is just a count of lookups with "..", which are not worth mentioniong.
