The branch main has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=2c7dd66d09a1b92a4698232996cded6e5315b3bd commit 2c7dd66d09a1b92a4698232996cded6e5315b3bd Author: Olivier Certner <olce.freebsd@certner.fr> AuthorDate: 2023-10-13 15:13:28 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2023-11-02 13:30:03 +0000 linuxkpi: dma_get_cache_alignment(): Fix off-by-one result Substituting 'uma_align_cache' by the appropriately named accessor uma_get_cache_align_mask() made apparent that dma_get_cache_alignment() was off by one, since it was defined to be the mask derived from the alignment value.
