The branch stable/15 has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=c358d6c0f350b64dd721581d115a231d365a119b commit c358d6c0f350b64dd721581d115a231d365a119b Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2025-12-08 16:15:52 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2025-12-19 15:19:44 +0000 proc0_post: Clear relevant thread stats directly rufetch() has several other effects besides clearing these per-thread stats most of which are explicitly discarded by the subsequent calls to ruxreset(). Just clear the relevant stats directly instead.
