From 84fa8af38d2eab0f72349abb8136811bd3e96570 Mon Sep 17 00:00:00 2001 From: Anand Avati Date: Tue, 24 Sep 2013 09:45:08 -0700 Subject: core: block unused signals in created threads Block all signal except those which are set for explicit handling in glusterfs_signals_setup(). Since thread spawning code in libglusterfs and xlators can get called from application threads when used through libgfapi, it is necessary to do this blocking.
