Subject: [PATCH 01/19] task_work: Remove dependency on sched.h
Date: Tue, 31 Jul 2012 21:12:05 +0200 [thread overview]
Message-ID: <20120731192808.397264606@chello.nl> (raw)
In-Reply-To: 20120731191204.540691987@chello.nl
[-- Attachment #1: decouple-sched-task_work.patch --]
[-- Type: text/plain, Size: 1160 bytes --]
Remove the need for sched.h from task_work.h so that we can use struct
task_work in struct task_struct in a later patch.
