The experimental user mode linux driver has some iNotify code in
it too if you want another point of reference. See the
umlInotifyEvent() method umlStartup() where I register for the
events
http://www.redhat.com/archives/libvir-list/2008-October/msg00355.html
Hum, the only problem is that contrary to uml , the xen drivers should
not be Linux specific, but inotify is linux specific.
Making this subdriver Linux only should still be okay until someone
using Solaris comes with an appropriate patch though,
/me hopes to never get involved again into the mess of portable APIs
for file changes notifications.
