Subject: [GIT PULL] workqueue for v2.6.37-rc1
Hello, Linus.
Please pull from the following branch to receive workqueue changes for
v2.6.37-rc1.
git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq.git for-linus
The branch contains the following notable changes.
* Fix for a subtle bug in HIGHPRI work handling where a HIGHPRI work
can be delayed by already executing non-HIGHPRI works.
* Addition of flush[_delayed]_work_sync(), which are equivalent to
cancel[_delayed]_work_sync() and make sure that the flushed work has
finished execution on all CPUs on return. This will be primarily
used to remove flush_scheduled_work() and other workqueue flushes
with work-specific flushes.
* Several patches removing the use of flush_scheduled_work(). There
are also multiple patches being routed through other subsystem
trees. Once the syncing variants of flush_work are available in
mainline, more will follow. The goal is to mark
flush_scheduled_work() deprecated in the next merge window and
remove it and trigger WARN_ON_ONCE() on all system workqueue flushes
in the one after that.
Pulling into the current mainline (d4429f60) generates the following
conflict in fs/gfs2/main.c. The resolution is WQ_MEM_RECLAIM |
WQ_FREEZEABLE.
@@@ -139,9 -143,9 +143,9 @@@ static int __init init_gfs2_fs(void
goto fail_unregister;
error = -ENOMEM;
gfs_recovery_wq = alloc_workqueue("gfs_recovery",
- WQ_NON_REENTRANT | WQ_MEM_RECLAIM, 0);
- WQ_RESCUER | WQ_FREEZEABLE, 0);
++ WQ_MEM_RECLAIM | WQ_FREEZEABLE, 0);
if (!gfs_recovery_wq)
goto fail_wq;
gfs2_register_debugfs();
Just in case, the merged branch is available in the following branch.
git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq.git merged
Thanks.
