inotify could easily solve the atime problem, but it's got the drawback of
forcing the user to register each and every file/dir of interest, which
isn't really reasonable on TB-filesystems.
It could be feasible to introduce mnotify, which would notify the user of
meta changes, like atime, across the filesystem. Something like mnotify
could also be helpful in CoW situations, provided it supported an in-sync
interface.
Thanks!
