sys/sys vnode.h mount.h
sys/ufs/ffs ffs_extern.h ffs_softdep.c ffs_vfsops.c
sys/ufs/ufs ufs_inode.c ufs_quota.c ufsmount.h
Log:
Use vn_start_secondary_write() and vn_finished_secondary_write() as a
replacement for vn_write_suspend_wait() to better account for secondary write
processing.
Close race where secondary writes could be started after ffs_sync() returned
but before the file system was marked as suspended.
Detect if secondary writes or softdep processing occurred during vnode sync
loop in ffs_sync() and retry the loop if needed.
