The branch main has been updated by rmacklem: URL: https://cgit.FreeBSD.org/src/commit/?id=8efba70d7914324890b1f8fe3079036eb2b5c3db commit 8efba70d7914324890b1f8fe3079036eb2b5c3db Author: Rick Macklem <rmacklem@FreeBSD.org> AuthorDate: 2024-04-25 19:32:02 +0000 Commit: Rick Macklem <rmacklem@FreeBSD.org> CommitDate: 2024-04-25 19:32:02 +0000 nfscl: Revert part of commit 196787f79e67 Commit 196787f79e67 erroneously assumed that the client code for Open/Claim_deleg_cur_FH was broken, but it was not. It was actually wireshark that was broken and indicated that the correct XDR was bogus. This reverts the part of 196787f79e67 that changed the arguments for Open/Claim_deleg_cur_FH. Found during the IETF bakeathon testing event this week.
