(In reply to Konstantin Belousov from comment #3)
I agree that we couldn't realistically generate a note each time a page is
dirtied.  I think the PR could be closed with "works as intended."

Maybe it would be useful to have an EVFILT_MMAP which generates notes any time
a given file is mapped or unmapped.
