Actually, poll(2) seems to have the same behaviour with a simpler test case (i.e. no epoll, & with just one fd being polled) - if I read(2) from it every few thousand usec (using the blktrace tool) it sees new data, but if I poll, it never reports the descriptor as changed (this is a 2.6.13 kernel with the relayfs patches from -mm patched into it and Jens' blktrace patch generating the data that I'm attempting to poll). cheers. -- Nathan - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
