  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.
