Konstantin Belousov 71f2642988 ufs: apply suspension for non-forced rw unmounts. ... Forced rw unmounts and remounts from rw to ro already suspend filesystem, which closes races with writers instantiating new vnodes while unmount flushes the queue. Original intent of not including non-forced unmounts into this regime was to allow such unmounts to fail if writer was active, but this did not worked well. Similar change, but causing all unmount, even involving only ro filesystem, were proposed in D24088, but I believe that suspending ro is undesirable, and definitely spends CPU time.
