The branch stable/13 has been updated by mckusick: URL: https://cgit.FreeBSD.org/src/commit/?id=cf1a6ffceec484f33807bab4bdb85d60b73ecff3 commit cf1a6ffceec484f33807bab4bdb85d60b73ecff3 Author: Kirk McKusick <mckusick@FreeBSD.org> AuthorDate: 2021-11-16 00:03:08 +0000 Commit: Kirk McKusick <mckusick@FreeBSD.org> CommitDate: 2022-08-17 22:49:09 +0000 Allow forced r/w mount of UFS/FFS filesystem with a bad check hash. Normally a UFS/FFS filesystem with a bad check hash can only be mounted read only. With this commit the mount(8) -f (force) option can be used to force a read-write mount of a UFS/FFS filesystem with a bad check hash. Conveniently the filesystem will proceed to update its on-disk superblock with a corrected check hash.
