The branch stable/14 has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=7bc713a5a5cf27140ad86a2ac805e9c0ea9bd083 commit 7bc713a5a5cf27140ad86a2ac805e9c0ea9bd083 Author: Mark Johnston <markj@FreeBSD.org> AuthorDate: 2023-12-26 01:43:21 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2024-01-02 00:29:58 +0000 nmount: Ignore errors when copying out an error string In general we copy error strings as part of reporting an error from lower layers, so if the copyout() fails there's nothing to do since we'd prefer to preserve the original error. This is in preparation for annotating copyin() and related functions with __result_use_check.
