2018-07-09ACPI / button: fix defined but not used warningRandy Dunlap1-1/+3
Fix a build warning in the ACPI button driver when CONFIG_PROC_FS is not enabled by marking the unused function as __maybe_unused. ../drivers/acpi/button.c:252:12: warning: 'acpi_button_state_seq_show' defined but not used [-Wunused-function] Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Rafael J.

2018-07-02ACPI / button: increment wakeup count only when notifiedRavi Chandra Sadineni1-6/+7
Because acpi_lid_initialize_state() is called on every system resume and it triggers acpi_lid_notify_state() which invokes acpi_pm_wakeup_event() for the lid device, the lid's wakeup count is incremented even if the lid was not the source of the event that woke up the system. That behavior confuses user space deamons using wakeup_count to identify the potential system wakeup source. To avoid the confusion, only trigger acpi_pm_wakeup_event() in the acpi_button_notify() path and don't do that in the acpi_lid_initialize_state() path.

Pull block fixes from Jens Axboe: "Small set of fixes for this series. Mostly just minor fixes, the only oddball in here is the sg change. The sg change came out of the stall fix for NVMe, where we added a mempool and limited us to a single page allocation. CONFIG_SG_DEBUG sort-of ruins that, since we'd need to account for that. That's actually a generic problem, since lots of drivers need to allocate SG lists. So this just removes support for CONFIG_SG_DEBUG, which I added back in 2007 and to my knowledge it was never useful.

2018-06-29blk-mq: don't queue more if we get a busy returnJens Axboe1-0/+12
Some devices have different queue limits depending on the type of IO. A classic case is SATA NCQ, where some commands can queue, but others cannot. If we have NCQ commands inflight and encounter a non-queueable command, the driver returns busy. Currently we attempt to dispatch more from the scheduler, if we were able to queue some commands. But for the case where we ended up stopping due to BUSY, we should not attempt to retrieve more from the scheduler. If we do, we can get into a situation where we attempt to queue a non-queueable command, get BUSY, then successfully retrieve more commands from that scheduler and queue those. This can repeat forever, starving the non-queuable command indefinitely. Fix this by NOT attempting to pull more commands from the scheduler, if we get a BUSY return. This should also be more optimal in terms of letting requests stay in the scheduler for as long as possible, if we get a BUSY due to the regular out-of-tags condition.

2018-06-29net: handle NULL ->poll gracefullyChristoph Hellwig1-0/+2
The big aio poll revert broke various network protocols that don't implement ->poll as a patch in the aio poll serie removed sock_no_poll and made the common code handle this case.

2018-06-29Revert "i2c: algo-bit: init the bus to a known state"Wolfram Sang1-5/+0
This reverts commit 3e5f06bed72fe72166a6778f630241a893f67799. As per bugzilla #200045, this caused a regression. I don't really see a way to fix it without having the hardware. So, revert the patch and I will fix the issue I was seeing originally in the i2c-gpio driver itself. I couldn't find new users of this algorithm since, so there should be no one depending on the new behaviour.

2018-06-28selinux: move user accesses in selinuxfs out of locked regionsJann Horn1-45/+33
If a user is accessing a file in selinuxfs with a pointer to a userspace buffer that is backed by e.g. a userfaultfd, the userspace access can stall indefinitely, which can block fsi->mutex if it is held. For sel_read_policy(), remove the locking, since this method doesn't seem to access anything that requires locking. For sel_read_bool(), move the user access below the locked region. For sel_write_bool() and sel_commit_bools_write(), move the user access up above the locked region.

2018-06-28dm: prevent DAX mounts if not supportedRoss Zwisler2-5/+5
Currently device_supports_dax() just checks to see if the QUEUE_FLAG_DAX flag is set on the device's request queue to decide whether or not the device supports filesystem DAX. Really we should be using bdev_dax_supported() like filesystems do at mount time. This performs other tests like checking to make sure the dax_direct_access() path works. We also explicitly clear QUEUE_FLAG_DAX on the DM device's request queue if any of the underlying devices do not support DAX. This makes the handling of QUEUE_FLAG_DAX consistent with the setting/clearing of most other flags in dm_table_set_restrictions(). Now that bdev_dax_supported() explicitly checks for QUEUE_FLAG_DAX, this will ensure that filesystems built upon DM devices will only be able to mount with DAX if all underlying devices also support DAX.

2018-06-28dax: check for QUEUE_FLAG_DAX in bdev_dax_supported()Ross Zwisler1-0/+8
Add an explicit check for QUEUE_FLAG_DAX to __bdev_dax_supported(). This is needed for DM configurations where the first element in the dm-linear or dm-stripe target supports DAX, but other elements do not. Without this check __bdev_dax_supported() will pass for such devices, letting a filesystem on that device mount with the DAX option.

QUEUE_FLAG_DAX is an indication that a given block device supports filesystem DAX and should not be set for PMEM namespaces which are in "raw" mode. These namespaces lack struct page and are prevented from participating in filesystem DAX as of commit 569d0365f571 ("dax: require 'struct page' by default for filesystem dax").
