From 8c0944cee7af55291df0b28e6e2eeac0930e93c9 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 7 Sep 2017 12:09:30 +0200 Subject: [PATCH] sched/deadline: Rename __dl_clear() to __dl_sub() __dl_sub() is more meaningful as a name, and is more consistent with the naming of the dual function (__dl_add()).
