Subject: [PATCH 3/11] pass task_struct in send_signal()
Date: Tue, 11 May 2004 01:48:33 -0700 [thread overview]
Message-ID: <20040511014833.B21045@build.pdx.osdl.net> (raw)
In-Reply-To: <20040511014639.A21045@build.pdx.osdl.net>; from chrisw@osdl.org on Tue, May 11, 2004 at 01:46:39AM -0700
Update send_signal() api to allow passing the task receiving the signal.
This is necessary to ensure signals generated out of process context can
be charged to the correct user.
