The branch main has been updated by andrew: URL: https://cgit.FreeBSD.org/src/commit/?id=8daee410d2c13b4e8530b00e7877eeecf30bb064 commit 8daee410d2c13b4e8530b00e7877eeecf30bb064 Author: Andrew Turner <andrew@FreeBSD.org> AuthorDate: 2023-11-29 12:11:37 +0000 Commit: Andrew Turner <andrew@FreeBSD.org> CommitDate: 2023-11-30 10:50:03 +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.
