That would be nice. It'd be great if there was a per-filesystem inotify
mode. I can't help but think it'd be more efficient than recursing
every directory and adding a watch.
Or maybe a netlink thing that could buffer events since filesystem mount
until a daemon could get around to starting, so none were lost.
See "Filesystem Event Reporter" by Yi Yang, that does pretty much
exactly that. http://lkml.org/lkml/2006/9/30/98 . Author had things to
update, never resubmitted it as far as I can tell.
