From 81dabb464139324c005159f5afba377104d8828d Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Wed, 3 Jul 2013 15:08:26 -0700 Subject: exit.c: unexport __set_special_pids() Move __set_special_pids() from exit.c to sys.c close to its single caller and make it static. And rename it to set_special_pids(), another helper with this name has gone away. Signed-off-by: Oleg Nesterov Cc: "Eric W.
