The branch main has been updated by dumbbell: URL: https://cgit.FreeBSD.org/src/commit/?id=002c08158f9e7eb61c467fe29ff8e24361fb8470 commit 002c08158f9e7eb61c467fe29ff8e24361fb8470 Author: Jean-Sébastien Pédron <dumbbell@FreeBSD.org> AuthorDate: 2026-04-21 00:32:18 +0000 Commit: Jean-Sébastien Pédron <dumbbell@FreeBSD.org> CommitDate: 2026-04-22 18:09:56 +0000 linuxkpi: Define `DIV_U64_ROUND_UP()` It is the same as `DIV64_U64_ROUND_UP()` but takes a 32-bit integer as the divisor. The amdgpu DRM driver started to use this in Linux 6.12.x.
