From 8fd66bec84a9724e4ef80c71cc149ab4165676fe Mon Sep 17 00:00:00 2001 From: Nick Ingolia Date: Thu, 14 Nov 2002 19:47:12 +0000 Subject: [PATCH] If ngroups in the parent is 0, but the first two elements of the groups array represent a valid PAG (perhaps because they weren't zeroed), then set_pag_in_parent won't add 2 to ngroups and the parent process won't join the PAG.
