Does poll handler is in interrupt context ?

[Ran Shalit]

Hello,

This is something I'm not too sure about, so I rather ask it here:
When the context return to userspace on calling poll, is it done in
interrupt context ?
...
ret = poll(fds, 2, TIMEOUT * 1000);
if (ret == -1) {
perror ("poll");
return 1;
}
if (!ret) {
return 0;
}
if (fds[0].revents & POLLIN)
printf ("POLLIN\n");
if (fds[1].revents & POLLOUT)
printf ("POLLOUT\n");
return 0;

Regards,
Ran
