re: CVS commit: src/sys/kern
Some of my changes occur hours after the last operations on the relevant
filesystem (if I forget, sometimes even days) - there's no rational chance
there is any unsync'd data (meta or otherwise) left anywhere. I really
you'd think that would be the case, but lots of inode atime updates
will likely be floating around the system not synced.
the workaround for that is to "cd /mnt; umount /mnt" which will fail
after it has written everything to disk.
i wonder if the ro->rw can abuse this path -- block new writes to the
fs and then do all the things unmount would do.
