From 9f59ce5d0e0dd837853385927b150f5cef3a7f52 Mon Sep 17 00:00:00 2001 From: Chuck Ebbert <76306.1226@compuserve.com> Date: Sat, 5 Aug 2006 12:14:11 -0700 Subject: [PATCH] [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.
