Hi Anders,
Here are my review comments. Not tested.
1. In osaf_ppoll(), until ppoll() is in real use.. can we keep the
logics simple to poll() <or> for now don't use osaf_ppoll() and let
the osaf_poll() take care calling poll() etc.
2. In osaf_ppoll(), for result = poll(), need to handle the case where
revents set to POLLNVAL.
3. Where ever pollfd struct is set/initialized with fd and POLLIN, also
please set revents=0;.
4. In nbconnect() of contrib/plmc/plmcd/plmcd.c: wset.events =
POLLOUT; should be wset.events = POLLIN;
This patch enforces to test OpenSAF thoroughly to handle all possible
cases of poll() usage.
Thanks,
Ramesh.
