The branch stable/14 has been updated by andrew: URL: https://cgit.FreeBSD.org/src/commit/?id=3736b79f0fa7655288f922d085b90eb5e0347067 commit 3736b79f0fa7655288f922d085b90eb5e0347067 Author: Andrew Turner <andrew@FreeBSD.org> AuthorDate: 2023-11-29 12:11:37 +0000 Commit: Andrew Turner <andrew@FreeBSD.org> CommitDate: 2024-09-02 08:43:01 +0000 vm: Use vmem_xalloc in kva_alloc The kernel_arena used in kva_alloc has the qcache disabled. vmem_alloc will first try to use the qcache before falling back to vmem_xalloc. Rather than trying to use the qcache in vmem_alloc just call vmem_xalloc directly.
