wine-staging/patches/server-JobObjects/0001-server-Basic-implementation-of-job-objects.-rev-2.patch

From fdec43a9ec165284f52d8ecd734abd6e2fe93d90 Mon Sep 17 00:00:00 2001
From: Andrew Cook <ariscop@gmail.com>
Date: Thu, 26 Feb 2015 12:25:23 +1100
Subject: server: Basic implementation of job objects. (rev 2)

This patch includes a (hopefully) complete implementation of process
tracking in job objects, but no limits or events outside of those.

This does not implement nested jobs as found in windows 8.

Changes by Sebastian Lackner <sebastian@fds-team.de>:
* Only use a single list instead of two for active / all processes.
* Various cleanups to fit with the rest of the wineserver coding style.

Changes in revision 2:
* Fix a wineserver crash when terminated processes are added to a job.
