From 2395140ee2bffe38b1c8a59318f62882b797f5e6 Mon Sep 17 00:00:00 2001 From: Davide Libenzi Date: Mon, 10 Apr 2006 22:54:12 -0700 Subject: [PATCH] [PATCH] uniform POLLRDHUP handling between epoll and poll/select As reported by Michael Kerrisk, POLLRDHUP handling was not consistent between epoll and poll/select, since in epoll it was unmaskeable. This patch brings uniformity in POLLRDHUP handling.
