Date: Tue, 1 Aug 2006 01:52:32 -0400 From: Chuck Ebbert <76306.1226@...puserve.com> To: linux-kernel <linux-kernel@...r.kernel.org> Cc: Andrew Morton <akpm@...l.org>, Daniel Jacobowitz <dan@...ian.org>, Linus Torvalds <torvalds@...l.org>, Albert Cahalan <acahalan@...il.com> Subject: [patch] ptrace: make pid of child process available for PTRACE_EVENT_VFORK_DONE When delivering PTRACE_EVENT_VFORK_DONE, provide pid of the child process when tracer calls ptrace(PTRACE_GETEVENTMSG). This is already (accidentally) available when the tracer is tracing VFORK in addition to VFORK_DONE.
