I think it uses linux_mmap then bouncing it to linux_mmap_common.
linux_mmap_common had it right but when it mmap picked it up then
it was wrong in my intrumentation.
I'll flip the l_off_t type back and then instrument it more to find
out when things are going bad. I missed the other usage of l_off_t
so I agree this is a bad change. However, I wonder if the other
usage of l_off_t actually works right or there is a bug with that
as well?
I should be able to get something put together pretty quick and
send it for review.
Thanks,
Doug A.
