Revision 00c10bc13cdb58447d6bb2a003afad7bd60f5a5f authored by Eric W. Biederman on 31 May 2012, 23:26:40 UTC, committed by Linus Torvalds on 01 June 2012, 00:49:32 UTC
Force SIGCHLD handling to SIG_IGN so that signals are not generated and so that the children autoreap. This increases the parallelize and in general the speed of network namespace shutdown. Note self reaping childrean can exist past zap_pid_ns_processess but they will all be reaped before we allow the pid namespace init task with pid == 1 to be reaped.
