From 4663d3e8f21652f33c698fcc2bf20f61499d9c3e Mon Sep 17 00:00:00 2001 From: Davidlohr Bueso Date: Wed, 14 Dec 2016 15:06:40 -0800 Subject: ipc/sem: explicitly inline check_restart The compiler already does this, but make it explicit. This helper is really small and also used in update_queue's main loop, which is O(N^2) scanning. Inline and avoid the function overhead.
