From 4ee5e4f30c874b5957f220c5263f75c40f7df501 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Mon, 22 Aug 2011 15:02:47 +0200 Subject: [PATCH] kill PF_STARTING Previously it was (ab)used by utrace. Then it was wrongly used by the scheduler code. Currently it is not used, kill it before it finds the new erroneous user.
