From e7c38cb49c6cc05bc11f70d9e9889da1c4a0d37f Mon Sep 17 00:00:00 2001 From: Con Kolivas Date: Fri, 31 Mar 2006 02:31:25 -0800 Subject: [PATCH] [PATCH] sched: make task_noninteractive use sleep_type Alterations to the pipe code in the kernel made it possible for relative starvation to occur with tasks that slept waiting on a pipe getting unfair priority bonuses even if they were otherwise fully cpu bound so the TASK_NONINTERACTIVE flag was introduced which prevented any change to sleep_avg while sleeping waiting on a pipe. This change also leads to the converse though, preventing any priority boost from occurring in truly interactive tasks that wait on pipes. Convert the TASK_NONINTERACTIVE flag to set sleep_type to SLEEP_NONINTERACTIVE which will allow a linear bonus to priority based on sleep time thus allowing interactive tasks to get high priority if they sleep enough.
