2007-05-24Fix crash with irqpoll due to the IRQF_IRQPOLL flag testingLinus Torvalds1-9/+37
With irqpoll enabled, trying to test the IRQF_IRQPOLL flag in the actions would cause a NULL pointer dereference if no action was installed (for example, the driver might have been unloaded with interrupts still pending). So be a bit more careful about testing the flag by making sure to test for that case. (The actual _change_ is trivial, the patch is more than a one-liner because I rewrote the testing to also be much more readable. Original (discarded) bugfix by Bernhard Walle.

2007-05-24NFS: Fix nfs_direct_dirty_pages()Trond Myklebust1-11/+18
We only need to dirty the pages that were actually read in. Also convert nfs_direct_dirty_pages() to call set_page_dirty() instead of set_page_dirty_lock(). A call to lock_page() is unacceptable in an rpciod callback function. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2007-05-24NFS: Avoid a deadlock situation on writeTrond Myklebust3-2/+25
When processes are allowed to attempt to lock a non-contiguous range of nfs write requests, it is possible for generic_writepages to 'wrap round' the address space, and call writepage() on a request that is already locked by the same process. We avoid the deadlock by checking if the page index is contiguous with the list of nfs write requests that is already held in our nfs_pageio_descriptor prior to attempting to lock a new request.

2007-05-24Prevent going idle with softirq pendingThomas Gleixner1-3/+1
The NOHZ patch contains a check for softirqs pending when a CPU goes idle. The BUG is unrelated to NOHZ, it just was made visible by the NOHZ patch. The BUG showed up mainly on P4 / hyperthreading enabled machines which lead the investigations into the wrong direction in the first place. The real cause is in cond_resched_softirq(): cond_resched_softirq() is enabling softirqs without invoking the softirq daemon when softirqs are pending. This leads to the warning message in the NOHZ idle code: t1 runs softirq disabled code on CPU#0 interrupt happens, softirq is raised, but deferred (softirqs disabled) t1 calls cond_resched_softirq() enables softirqs via _local_bh_enable() calls schedule() t2 runs t1 is migrated to CPU#1 t2 is done and invokes idle() NOHZ detects the pending softirq Fix: change _local_bh_enable() to local_bh_enable() so the softirq daemon is invoked.

2007-05-24simplify cleanup_workqueue_thread()Oleg Nesterov1-47/+37
cleanup_workqueue_thread() and cwq_should_stop() are overcomplicated. Convert the code to use kthread_should_stop/kthread_stop as was suggested by Gautham and Srivatsa. In particular this patch removes the (unlikely) busy-wait loop from the exit path, it was a temporary and ugly kludge (if not a bug). Note: the current code was designed to solve another old problem: work->func can't share locks with hotplug callbacks. I think this could be done, see http://marc.info/?l=linux-kernel&m=116905366428633 but this needs some more complications to preserve CPU affinity of cwq->thread during cpu_up(). A freezer-based hotplug looks more appealing.
