Its used both for configuring the hardware and for transmitting IR data. In the tx case, mce_request_packet actually allocates both a urb and the transfer buffer, neither of which was being torn down. Do that in the tx callback.

Ergo, remove them all, and rename the one and only (questionably) useful one to reflect what it really does. Verified on both gen2 and gen3 hardware to make zero difference. Well, except that you no longer get a bunch of urb submit failures from the unneeded mce_sync_in calls. Oh. And move that flush to a point *after* we've wired up the inbound urb, or it won't do squat. I have half a mind to just remove it entirely, but someone thought it was necessary at some point, and it doesn't seem to hurt, so lets leave it for the time being. This excercise took place due to insightful questions asked by Hans Petter Selasky, about the possible reuse of the inbound urb before it was actually availble by mce_sync_in, so thanks to him for motivating this cleanup.

For example, if the client falls back on 4.0, or falls back to MDS IO because the user didn't connect to the right iscsi disks before mounting, the only symptoms may be reduced performance, which may not be noticed till long after the actual failure, and may be difficult for a user to diagnose.

| bda8efe | Mikulas Patocka | 29 May 2011, 12:03:09 UTC | dm io: use fixed initial mempool size Replace the arbitrary calculation of an initial io struct mempool size with a constant. The code calculated the number of reserved structures based on the request size and used a "magic" multiplication constant of 4. This patch changes it to reserve a fixed number - itself still chosen quite arbitrarily. Further testing might show if there is a better number to choose. Note that if there is no memory pressure, we can still allocate an arbitrary number of "struct io" structures. One structure is enough to process the whole request.

| 4cc1b4c | Mikulas Patocka | 29 May 2011, 12:03:02 UTC | dm kcopyd: remove superfluous page allocation spinlock Remove the spinlock protecting the pages allocation. The spinlock is only taken on initialization or from single-threaded workqueue. Therefore, the spinlock is useless. The spinlock is taken in kcopyd_get_pages and kcopyd_put_pages. kcopyd_get_pages is only called from run_pages_job, which is only called from process_jobs called from do_work. kcopyd_put_pages is called from client_alloc_pages (which is initialization function) or from run_complete_job. run_complete_job is only called from process_jobs called from do_work. Another spinlock, kc->job_lock is taken each time someone pushes or pops some work for the worker thread. Once we take kc->job_lock, we guarantee that any written memory is visible to the other CPUs.

| c6ea41f | Mikulas Patocka | 29 May 2011, 12:03:00 UTC | dm kcopyd: preallocate sub jobs to avoid deadlock There's a possible theoretical deadlock in dm-kcopyd because multiple allocations from the same mempool are required to finish a request. Avoid this by preallocating sub jobs. There is a mempool of 512 entries. Each request requires up to 9 entries from the mempool. If we have at least 57 concurrent requests running, the mempool may overflow and mempool allocations may start blocking until another entry is freed to the mempool. Because the same thread is used to free entries to the mempool and allocate entries from the mempool, this may result in a deadlock. This patch changes it so that one mempool entry contains all 9 "struct kcopyd_job" required to fulfill the whole request. The allocation is done only once in dm_kcopyd_copy and no further mempool allocations are done during request processing. If dm_kcopyd_copy is not run in the completion thread, this implementation is deadlock-free. MIN_JOBS needs reducing accordingly and we've chosen to reduce it further to 8.

| f4808ca | Milan Broz | 29 May 2011, 12:02:52 UTC | dm table: reject devices without request fns This patch adds a check that a block device has a request function defined before it is used. Otherwise, misconfiguration can cause an oops. Because we are allowing devices with zero size e.g. an offline multipath device as in commit 2cd54d9bedb79a97f014e86c0da393416b264eb3 ("dm: allow offline devices") there needs to be an additional check to ensure devices are initialised. Some block devices, like a loop device without a backing file, exist but have no request function. Reproducer is trivial: dm-mirror on unbound loop device (no backing file on loop devices) dmsetup create x --table "0 8 mirror core 2 8 sync 2 /dev/loop0 0 /dev/loop1 0" and mirror resync will immediatelly cause OOps.

| 3c5cffb | Heiko Carstens | 29 May 2011, 10:40:51 UTC | [S390] mm: fix mmu_gather rework Quite a few functions that get called from the tlb gather code require that preemption must be disabled. So disable preemption inside of the called functions instead. The only drawback is that rcu_table_freelist_finish() doesn't get necessarily called on the cpu(s) that filled the free lists. So we may see a delay, until we finally see an rcu callback. However over time this shouldn't matter. So we get rid of lots of "BUG: using smp_processor_id() in preemptible" messages.

This got inconsistent with 2d42552d "[S390] merge page_test_dirty and page_clear_dirty". Result is that we read/write storage keys from random pages and do not have a working dirty bit tracking at all. E.g. SetPageUpdate() doesn't clear the dirty bit of requested pages, which for example ext4 doesn't like very much and panics after a while.
