From e7ca2a51a89a8ff2c9f5adfdfa5b51be1b3faeb3 Mon Sep 17 00:00:00 2001 From: Bhasker Hariharan Date: Wed, 24 Mar 2021 12:08:24 -0700 Subject: Add POLLRDNORM/POLLWRNORM support. On Linux these are meant to be equivalent to POLLIN/POLLOUT. Rather than hack these on in sys_poll etc it felt cleaner to just cleanup the call sites to notify for both events. This is what linux does as well.
