>From the kqueue(2) manual:

"""
     EVFILT_VNODE   Takes a file descriptor as the identifier and the events
                    to watch for in fflags, and returns when one or more of
                    the requested events occurs on the descriptor.  The
events
                    to monitor are:...
"""

I'm interested in NOTE_WRITE, but is there a way to find out where has
