The branch main has been updated by kib: URL: https://cgit.FreeBSD.org/src/commit/?id=50acaaef54b4d7811393eb8c05a398d7a1882418 commit 50acaaef54b4d7811393eb8c05a398d7a1882418 Author: Konstantin Belousov <kib@FreeBSD.org> AuthorDate: 2021-06-15 10:27:37 +0000 Commit: Konstantin Belousov <kib@FreeBSD.org> CommitDate: 2021-06-23 20:47:05 +0000 ffs_softdep: force sync if journal is low in journal_check_space This effectively causes syncing of the mount point from softdep_prealloc(), softdep_prerename(), and softdep_prelink(). Typically it avoids the need for journal suspension at this point, at all.
