Subject: [patch 02/23] [PATCH] Dont auto-reap traced children
Date: Tue, 22 Nov 2005 13:06:07 -0800 [thread overview]
Message-ID: <20051122210607.GC28140@shell0.pdx.osdl.net> (raw)
[-- Attachment #1: ptrace-auto-reap-fix.patch --]
[-- Type: text/plain, Size: 866 bytes --]
-stable review patch. If anyone has any objections, please let us know.
------------------
If a task is being traced we never auto-reap it even if it might look
like its parent doesn't care. The tracer obviously _does_ care.
