Date: Sat, 28 Nov 2015 21:46:10 -0500 From: Antoine Busque <abusque@...icios.com> To: mingo@...hat.com Cc: peterz@...radead.com, linux-kernel@...r.kernel.org Subject: [PATCH] sched: fix outdated comment on task_prio() return value The comment describing the possible return values of the task_prio() function, having not been updated in many years, was misleading. It indicated an offset of -200 for RT tasks, and normal tasks having 32 possible priority values centered around 0. This is no longer the case, as the values it returns will be in the range [-100..39]. The new comment reflects the current behaviour.
