Subject: [LTP] [PATCH] ptrace/ptrace05: preventing kill other processes if fork failed
Date: Tue, 12 Apr 2016 11:07:34 +0800	[thread overview]
Message-ID: <20160412030734.GA11627@localhost.localdomain> (raw)

If fork failed, we should try next signum. Or the kill(-1, 9) on line
196 will kill a lot of processes.
