I'm not touching that code except to send out possible patches for others
to test and comment on. I have no test-cases, nor any real interest in it.
So yeah, please send me a tested and thought-through patch.
It sounded like Karl actually had a test-case to trigger this, but maybe
I'm confused (and it sounds a bit unlikely, since it should be hard to
trigger.. Although maybe you can trigger it by doing a direct_IO write
with the *source* being an mmap() of the file you're writing to, and
depending on the write itself re-populating the destination in the page
cache?)
Karl?
