The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=918966a27479b4fb7c4c8999c4926d83c2c081e5 commit 918966a27479b4fb7c4c8999c4926d83c2c081e5 Author: Jake Freeland <jfree@FreeBSD.org> AuthorDate: 2023-09-05 22:13:23 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2023-09-05 22:25:07 +0000 timerfd: Relocate 32-bit compat code 32-bit compatibility code is conventionally stored in sys/compat/freebsd32. Move freebsd32_timerfd_gettime() and freebsd32_timerfd_settime() from sys/kern/sys_timerfd.c to sys/compat/freebsd32/freebsd32_misc.c.
