From 77097ae503b170120ab66dd1d547f8577193f91f Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 27 Apr 2012 13:58:59 -0400 Subject: most of set_current_blocked() callers want SIGKILL/SIGSTOP removed from set Only 3 out of 63 do not. Renamed the current variant to __set_current_blocked(), added set_current_blocked() that will exclude unblockable signals, switched open-coded instances to it.
