Many thanks to Josef, Miao Xie, and Dave Sterba for nailing it all down. Miao also has a new OOM fix in this v2 pull as well. Ilya fixed a regression Liu Bo found in the balance ioctls for pausing and resuming a running balance across drives. Josef's orphan truncate patch fixes an obscure corruption we'd see during xfstests. Arne's patches address problems with subvolume quotas. If the user destroys quota groups incorrectly the FS will refuse to mount. The rest are smaller fixes and plugs for memory leaks." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (30 commits) Btrfs: fix repeated delalloc work allocation Btrfs: fix wrong max device number for single profile Btrfs: fix missed transaction->aborted check Btrfs: Add ACCESS_ONCE() to transaction->abort accesses Btrfs: put csums on the right ordered extent Btrfs: use right range to find checksum for compressed extents Btrfs: fix panic when recovering tree log Btrfs: do not allow logged extents to be merged or removed Btrfs: fix a regression in balance usage filter Btrfs: prevent qgroup destroy when there are still relations Btrfs: ignore orphan qgroup relations Btrfs: reorder locks and sanity checks in btrfs_ioctl_defrag Btrfs: fix unlock order in btrfs_ioctl_rm_dev Btrfs: fix unlock order in btrfs_ioctl_resize Btrfs: fix "mutually exclusive op is running" error code Btrfs: bring back balance pause/resume logic btrfs: update timestamps on truncate() btrfs: fix btrfs_cont_expand() freeing IS_ERR em Btrfs: fix a bug when llseek for delalloc bytes behind prealloc extents Btrfs: fix off-by-one in lseek ... 25 January 2013, 18:55:21 UTC

1eafa6c Miao Xie 22 January 2013, 10:49:00 UTC Btrfs: fix repeated delalloc work allocation btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/ btrfs_queue_worker for this inode, and then it locks the list, checks the head of the list again. But because we don't delete the first inode that it deals with before, it will fetch the same inode. As a result, this function allocates a huge amount of btrfs_delalloc_work structures, and OOM happens. Fix this problem by splice this delalloc list.

2cba30f Miao Xie 15 January 2013, 06:29:12 UTC Btrfs: fix missed transaction->aborted check First, though the current transaction->aborted check can stop the commit early and avoid unnecessary operations, it is too early, and some transaction handles don't end, those handles may set transaction->aborted after the check. Second, when we commit the transaction, we will wake up some worker threads to flush the space cache and inode cache. Those threads also allocate some transaction handles and may set transaction->aborted if some serious error happens. So we need more check for ->aborted when committing the transaction. Fix it.

e58dd74 Josef Bacik 22 January 2013, 20:43:09 UTC Btrfs: put csums on the right ordered extent I noticed a WARN_ON going off when adding csums because we were going over the amount of csum bytes that should have been allowed for an ordered extent. This is a leftover from when we used to hold the csums privately for direct io, but now we use the normal ordered sum stuff so we need to make sure and check if we've moved on to another extent so that the csums are added to the right extent. Without this we could end up with csums for bytenrs that don't have extents to cover them yet. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com> 24 January 2013, 17:51:22 UTC

b017511 Josef Bacik 18 December 2012, 16:39:19 UTC Btrfs: fix panic when recovering tree log A user reported a BUG_ON(ret) that occured during tree log replay. Ret was -EAGAIN, so what I think happened is that we removed an extent that covered a bitmap entry and an extent entry. We remove the part from the bitmap and return -EAGAIN and then search for the next piece we want to remove, which happens to be an entire extent entry, so we just free the sucker and return. The problem is ret is still set to -EAGAIN so we trip the BUG_ON(). The user used btrfs-zero-log so I'm not 100% sure this is what happened so I've added a WARN_ON() to catch the other possibility.

201a903 Josef Bacik 24 January 2013, 17:02:07 UTC Btrfs: do not allow logged extents to be merged or removed We drop the extent map tree lock while we're logging extents, so somebody could come in and merge another extent into this one and screw up our logging, or they could even remove us from the list which would keep us from logging the extent or freeing our ref on it, so we need to make sure to not clear LOGGING until after the extent is logged, and then we can merge it to adjacent extents.

31614bb Takashi Iwai 23 January 2013, 14:58:40 UTC ALSA: hda - Fix inconsistent pin states after resume The commit [26a6cb6c: ALSA: hda - Implement a poll loop for jacks as a module parameter] introduced the polling jack detection code, but it also moved the call of snd_hda_jack_set_dirty_all() in the resume path after resume/init ops call. This caused a regression when the jack state has been changed during power-down (e.g. in the power save mode). Since the driver doesn't probe the new jack state but keeps using the cached value due to no dirty flag, the pin state remains also as if the jack is still plugged. The fix is simply moving snd_hda_jack_set_dirty_all() to the original position.

f56c319 Tejun Heo 23 January 2013, 00:15:15 UTC async: fix __lowest_in_progress() Commit 083b804c4d3e ("async: use workqueue for worker pool") made it possible that async jobs are moved from pending to running out-of-order. While pending async jobs will be queued and dispatched for execution in the same order, nothing guarantees they'll enter "1) move self to the running queue" of async_run_entry_fn() in the same order. Before the conversion, async implemented its own worker pool. An async worker, upon being woken up, fetches the first item from the pending list, which kept the executing lists sorted. The conversion to workqueue was done by adding work_struct to each async_entry and async just schedules the work item. The queueing and dispatching of such work items are still in order but now each worker thread is associated with a specific async_entry and moves that specific async_entry to the executing list. So, depending on which worker reaches that point earlier, which is non-deterministic, we may end up moving an async_entry with larger cookie before one with smaller one. This broke __lowest_in_progress(). running->domain may not be properly sorted and is not guaranteed to contain lower cookies than pending list when not empty. Fix it by ensuring sort-inserting to the running list and always looking at both pending and running when trying to determine the lowest cookie. Over time, the async synchronization implementation became quite messy. We better restructure it such that each async_entry is linked to two lists - one global and one per domain - and not move it when execution starts. There's no reason to distinguish pending and running. They behave the same for synchronization purposes.

9899d11 Oleg Nesterov 21 January 2013, 19:48:00 UTC ptrace: ensure arch_ptrace/ptrace_request can never race with SIGKILL putreg() assumes that the tracee is not running and pt_regs_access() can safely play with its stack. However a killed tracee can return from ptrace_stop() to the low-level asm code and do RESTORE_REST, this means that debugger can actually read/modify the kernel stack until the tracee does SAVE_REST again. set_task_blockstep() can race with SIGKILL too and in some sense this race is even worse, the very fact the tracee can be woken up breaks the logic. As Linus suggested we can clear TASK_WAKEKILL around the arch_ptrace() call, this ensures that nobody can ever wakeup the tracee while the debugger looks at it. Not only this fixes the mentioned problems, we can do some cleanups/simplifications in arch_ptrace() paths. Probably ptrace_unfreeze_traced() needs more callers, for example it makes sense to make the tracee killable for oom-killer before access_process_vm(). While at it, add the comment into may_ptrace_stop() to explain why ptrace_stop() still can't rely on SIGKILL and signal_pending_state().

If the IRQ line is shared with other devices, it's possible for the handler routine to be called before the data structures are fully initialized. The problem is fixed by adding a check to the IRQ handler routine. If the initialization hasn't finished yet, the routine will return immediately.

910ffdb Oleg Nesterov 21 January 2013, 19:47:41 UTC ptrace: introduce signal_wake_up_state() and ptrace_signal_wake_up() Cleanup and preparation for the next change. signal_wake_up(resume => true) is overused. None of ptrace/jctl callers actually want to wakeup a TASK_WAKEKILL task, but they can't specify the necessary mask. Turn signal_wake_up() into signal_wake_up_state(state), reintroduce signal_wake_up() as a trivial helper, and add ptrace_signal_wake_up() which adds __TASK_TRACED. This way ptrace_signal_wake_up() can work "inside" ptrace_request() even if the tracee doesn't have the TASK_WAKEKILL bit set.

9eb13cf Aaro Koskinen 20 January 2013, 18:37:02 UTC i2c: omap: fix draining irq handling Commit 0bdfe0cb803dce699ff337c35d8e97ac355fa417 (i2c: omap: sanitize exit path) changed the interrupt handler to exit early and complete the transfer after the draining IRQ is handled. As a result, the ARDY may not be cleared properly, and it may cause all future I2C transfers to timeout with "timeout waiting for bus ready". This is reproducible at least with N900 when twl4030_gpio makes a long write (> FIFO size) during the probe (http://marc.info/?l=linux-omap&m=135818882610432&w=2). The fix is to continue until we get ARDY interrupt that completes the transfer. Tested with 3.8-rc4 + N900: 20 boots in a row without errors; without the patch the problem triggers after few reboots.

9855d8c Stefan Bader 22 January 2013, 12:37:21 UTC ACPI: Check MSR valid bit before using P-state frequencies To fix incorrect P-state frequencies which can happen on some AMD systems f594065faf4f9067c2283a34619fc0714e79a98d "ACPI: Add fixups for AMD P-state figures" introduced a quirk to obtain the correct values by reading from AMD specific MSRs. This did cause a regression when running a kernel using that quirk under Xen which does (currently) not pass through MSR reads to the HW. Instead the guest gets a 0 in return. And this seems to cause a failure to initialize the ondemand governour (hard to say for sure as all P-states appear to run at the same frequency). While this should also be fixed in the hypervisor (to allow a guest to read that MSR), this patch is intended to work around the issue in the meantime. In discussion it turned out that indeed real HW/BIOSes may choose to not set the valid bit and thus mark the P-state as invalid. So this could be considered a fix for broken BIOSes that also works around the issue on Xen.

Unfortunately, the current exynos4 busfreq driver does not honor the usage constraint and stores the OPP pointer in struct busfreq_data. This could potentially become invalid later such as: across devfreq opp change decisions, resulting in unpredictable behavior. To fix this, we introduce a busfreq specific busfreq_opp_info structure which is used to handle OPP information. OPP information is de-referenced to voltage and frequency pairs as needed into busfreq_opp_info structure and used as needed. Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Rafael J.
