The branch main has been updated by mav: URL: https://cgit.FreeBSD.org/src/commit/?id=358453ce9bdd99eb69641b02f2d7e29cedecbe27 commit 358453ce9bdd99eb69641b02f2d7e29cedecbe27 Author: Alexander Motin <mav@FreeBSD.org> AuthorDate: 2023-12-27 00:36:34 +0000 Commit: Alexander Motin <mav@FreeBSD.org> CommitDate: 2023-12-27 00:36:34 +0000 iichid(4): Switch taskqueue to "fast" While "fast" taskqueue may be more expensive due to spinlock use, when used mainly for timeout tasks it allows to avoid extra context switches to and from callout thread, that is even more expensive.
