Konstantin Belousov bda2eb9ae8 Refine r280308. Do not completely disable timestamping of devfs nodes ... on reads or writes, the time marks are used to display idle time by w(1) [1]. Instead, use vfs.devfs.dotimes as the selector of default precision vs. using time_second. The later gives seconds precision, which is good enough for the purpose. Note that timestamp updates are unlocked and the updates itself, as well as the check in devfs_timestamp, are non-atomic.
