We're doing some testing with openib btl on a system with Solaris.  It looks like Solaris can return POLLIN|POLLRDNORM in revents from a poll call.  I looked at the manpages for Linux and it reads like Linux could possibly do this too.  However the code in btl_openib_async_thread that checks for valid revents is only checking for POLLIN and in the case it gets POLLIN|POLLRDNORM the btl ends up throwing an error.  I think erroring out on the POLLIN|POLLRDNORM case is a bug.

Does anyone feel otherwise and can explain to me why we should not consider POLLIN|POLLRDNORM as a valid condition?  I have the same question pertaining to POLLRDBAND too but I don't believe we've seen this set.
