The branch releng/13.1 has been updated by kp: URL: https://cgit.FreeBSD.org/src/commit/?id=81c1d7c9c727184dacb31df563fb42d208ccde46 commit 81c1d7c9c727184dacb31df563fb42d208ccde46 Author: Kristof Provost <kp@FreeBSD.org> AuthorDate: 2022-03-17 02:35:13 +0000 Commit: Kristof Provost <kp@FreeBSD.org> CommitDate: 2022-03-20 15:25:40 +0000 if_epair: build fix 66acf7685b failed to build on riscv (and mips). This is because the atomic_testandset_int() (and friends) functions do not exist there. Happily those platforms do have the long variant, so switch to that.
