Simply the normal shutdown procedure: notifying the startup process that it should notify the filesystem processes, which make the filesystems read-only, write what's pending, and then we can reboot with not too much harm. Another way is to use reboot-hurd instead of reboot. But one may not even have access to a prompt to type it, thus having a keyboard shortcut that works all the time. > On Linux, for processes which are blocked (maybe of CPU) are in Deep > Uninterruptible State.
