[PATCHSET] workqueue: another assorted flush_scheduled_work() removals

[Tejun Heo <tj@kernel.org>]

Hello,

This is another set of patches to remove flush_scheduled_work() users.

 0001-init-don-t-call-flush_scheduled_work-from-do_initcal.patch
 0002-ioc4-use-static-work_struct-for-ioc4_load_modules.patch
 0003-media-video-explicitly-flush-request_module-work.patch
 0004-media-video-don-t-use-flush_scheduled_work.patch
 0005-speedtch-don-t-abuse-struct-delayed_work.patch
 0006-usb-don-t-use-flush_scheduled_work.patch

Andrew, implementing proper work function in init text test requires
tracking an additional state for each worker.  I don't think it'll be
worth the effort or complexity as removal of init sections itself will
make the bugs, if exists, quite visible anyway, so I just updated
patch description of 0001.  What do you think?

0002 updates the ioc4 driver to use static work_struct and removes
flush_scheduled_work() call in the process.

0003-0004 convert the video drivers and 0005-0006 usb.

These patches are available in the following git tree.

 git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq.git net-dev-kill-flush_scheduled_work

Note that the branch is on top of the previous set of
flush_scheduled_work() removal patches; however, they're independent
and this series cleanly applies on top of 2.6.37-rc5
(6313e3c21743cc88bb5bd8aa72948ee1e83937b6).

diffstat follows.  Thanks.
