The branch stable/12 has been updated by rmacklem: URL: https://cgit.FreeBSD.org/src/commit/?id=5713766d631787677a291490e0b8e369d30be43e commit 5713766d631787677a291490e0b8e369d30be43e Author: Rick Macklem <rmacklem@FreeBSD.org> AuthorDate: 2021-05-21 01:37:40 +0000 Commit: Rick Macklem <rmacklem@FreeBSD.org> CommitDate: 2021-06-04 03:27:05 +0000 nfsd: Add support for CLAIM_DELEG_PREV_FH to the NFSv4.1/4.2 Open Commit b3d4c70dc60f added support for CLAIM_DELEG_CUR_FH to Open. While doing this, I noticed that CLAIM_DELEG_PREV_FH support could be added the same way. Although I am not aware of any extant NFSv4.1/4.2 client that uses this claim type, it seems prudent to add support for this variant of Open to the NFSv4.1/4.2 server. This patch does not affect mounts from extant NFSv4.1/4.2 clients, as far as I know.
