Subject: [PATCH 5/5] kernel/cpu.c: make set_cpu_xyz static inlines
Date: Thu, 7 May 2015 00:52:54 +0200 [thread overview]
Message-ID: <1430952775-4266-6-git-send-email-linux@rasmusvillemoes.dk> (raw)
In-Reply-To: <1430952775-4266-1-git-send-email-linux@rasmusvillemoes.dk>
Almost all callers of the set_cpu_xyz functions pass an explicit true
or false. Making them static inline thus replaces the function calls
with a simple set_bit/clear_bit, saving some .text.
