--- Comment #4 from Peter Wemm <peter at FreeBSD.org> ---
FWIW; the thought experiment patch is wrong - it does not implement what I
thought it did.
I still think it is probably the best option though. The root of the problem
is the read-ahead and we cannot trust size reporting. The old code did not do
read-ahead. Preventing read-ahead from crossing the end of disk, or an alias of
the end of disk should be more than sufficient to restore old behavior without
adding new hard failure cases.
