[PATCH 3.14 34/42] sched: declare pid_alive as inline

From: Greg Kroah-Hartman
Date: Sun Apr 26 2015 - 10:10:28 EST

3.14-stable review patch. If anyone has any objections, please let me know.


From: Richard Guy Briggs <rgb@xxxxxxxxxx>

commit 80e0b6e8a001361316a2d62b748fe677ec46b860 upstream.

We accidentally declared pid_alive without any extern/inline connotation.
Some platforms were fine with this, some like ia64 and mips were very angry.
If the function is inline, the prototype should be inline!

on ia64:
include/linux/sched.h:1718: warning: 'pid_alive' declared inline after
being called
