The branch stable/15 has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=c24d1d070475daa23bba9aaebdb2370e16e74d72 commit c24d1d070475daa23bba9aaebdb2370e16e74d72 Author: Jean-Sébastien Pédron <dumbbell@FreeBSD.org> AuthorDate: 2025-08-12 21:55:04 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2026-04-22 20:56:56 +0000 linuxkpi: Define `raw_spinlock_t` in <linux/spinlock.h> For now, it is synonymous to `spinlock_t`. The DRM generic code uses the `struct raw_spinlock` and not `raw_spinlock_t`, that's why the definition is a struct embedding a `struct mtx`, compared to `spinlock_t` which is a simpler typedef. The DRM generic code started to use it in Linux 6.10.
