The branch stable/13 has been updated by mjg: URL: https://cgit.FreeBSD.org/src/commit/?id=f1c39eb170ddeca5137edb706d89216f5a1a1d4f commit f1c39eb170ddeca5137edb706d89216f5a1a1d4f Author: Mateusz Guzik <mjg@FreeBSD.org> AuthorDate: 2021-06-30 14:15:25 +0000 Commit: Mateusz Guzik <mjg@FreeBSD.org> CommitDate: 2021-07-05 12:04:59 +0000 mbuf: add m_free_raw to be used instead of directly calling uma_zfree The intent is to remove all direct zone_mbuf consumers so that ctor/dtor from that zone can be reimplemented as wrappers around uma, avoiding an indirect function call.
