When multiple thermal zones are bound to the same cooling device, multiple kernel threads may want to update the cooling device state by calling thermal_cdev_update(). Having cdev not protected by a mutex can lead to a race condition. Consider the following situation with two kernel threads k1 and k2: Thread k1 Thread k2 || || call thermal_cdev_update() || ... || set_cur_state(cdev, target); call power_actor_set_power() || ... || instance->target = state; || cdev->updated = false; || || cdev->updated = true; || // completes execution call thermal_cdev_update() || // cdev->updated == true || return; || \/ time k2 has already looped through the thermal instances looking for the deepest cooling device state and is preempted right before setting cdev->updated to true. Now, k1 runs, modifies the thermal instance state and sets cdev->updated to false. Then, k1 is preempted and k2 continues the execution by setting cdev->updated to true, therefore preventing k1 from performing the update. Notice that this is not an issue if k2 looks at the instance->target modified by k1 "after" it is assigned by k1. In fact, in this case the update will happen anyway and k1 can safely return immediately from thermal_cdev_update(). This may lead to a situation where a thermal governor never updates the cooling device. For example, this is the case for the step_wise governor: when calling the function thermal_zone_trip_update(), the governor may always get a new state equal to the old one (which, however, wasn't notified to the cooling device) and will therefore skip the update.

Since commit 63a4cc24, bio->bi_rw contains flags in the lower portion and the op code in the higher portions. This means that old code that relies on manually setting bi_rw is most likely going to be broken. Instead of letting that brokeness linger, rename the member, to force old and out-of-tree code to break at compile time instead of at runtime. No intended functional changes in this commit.

Commit abf54548 changed it from an 'rw' flags type to the newer ops based interface, but now we're effectively leaking some bdev internals to the rest of the kernel. Since we only care about whether it's a read or a write at that level, just pass in a bool 'is_write' parameter instead. Then we can also move op_is_write() and friends back under CONFIG_BLOCK protection. Reviewed-by: NMike Christie <mchristi@redhat.com> Signed-off-by: NJens Axboe <axboe@fb.com>

Merge tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs Pull more xfs updates from Dave Chinner: "This is the second part of the XFS updates for this merge cycle, and contains the new reverse block mapping feature for XFS. Reverse mapping allows us to track the owner of a specific block on disk precisely. It is implemented as a set of btrees (one per allocation group) that track the owners of allocated extents. Effectively it is a "used space tree" that is updated when we allocate or free extents. i.e. it is coherent with the free space btrees we already maintain and never overlaps with them. This reverse mapping infrastructure is the building block of several upcoming features - reflink, copy-on-write data, dedupe, online metadata and data scrubbing, highly accurate bad sector/data loss reporting to users, and significantly improved reconstruction of damaged and corrupted filesystems. There's a lot of new stuff coming along in the next couple of cycles,a nd it all builds in the rmap infrastructure. As such, it's a huge chunk of new code with new on-disk format features and internal infrastructure. It warns at mount time as an experimental feature and that it may eat data (as we do with all new on-disk features until they stabilise). We have not released userspace suport for it yet - userspace support currently requires download from Darrick's xfsprogs repo and build from source, so the access to this feature is really developer/tester only at this point. Initial userspace support will be released at the same time kernel with this code in it is released. The new rmap enabled code regresses 3 xfstests - all are ENOSPC related corner cases, one of which Darrick posted a fix for a few hours ago. The other two are fixed by infrastructure that is part of the upcoming reflink patchset. This new ENOSPC infrastructure requires a on-disk format tweak required to keep mount times in check - we need to keep an on-disk count of allocated rmapbt blocks so we don't have to scan the entire btrees at mount time to count them. This is currently being tested and will be part of the fixes sent in the next week or two so users will not be exposed to this change" * tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (52 commits) xfs: move (and rename) the deferred bmap-free tracepoints xfs: collapse single use static functions xfs: remove unnecessary parentheses from log redo item recovery functions xfs: remove the extents array from the rmap update done log item xfs: in btree_lshift, only allocate temporary cursor when needed xfs: remove unnecesary lshift/rshift key initialization xfs: remove the get*keys and update_keys btree ops pointers xfs: enable the rmap btree functionality xfs: don't update rmapbt when fixing agfl xfs: disable XFS_IOC_SWAPEXT when rmap btree is enabled xfs: add rmap btree block detection to log recovery xfs: add rmap btree geometry feature flag xfs: propagate bmap updates to rmapbt xfs: enable the xfs_defer mechanism to process rmaps to update xfs: log rmap intent items xfs: create rmap update intent log items xfs: add rmap btree insert and delete helpers xfs: convert unwritten status of reverse mappings xfs: remove an extent from the rmap btree xfs: add an extent to the rmap btree ...

Pull more ACPI updates from Rafael Wysocki: "Two more fixes in ACPI drivers, one in the ACPI EC driver (stable-candidate) and one in the ACPI button driver. Specifics: - An ACPI EC driver fix from the 4.3 cycle may cause the ACPICA's method reentrancy limit to be exceeded for a _Qxx method due to a large number of concurrent EC operations, so prevent that from happening by moving the EC handling into a separate workqueue with a limit on the number of concurrently executed work items (Lv Zheng) - Fix the cleanup code in the ACPI button driver that forgets to clear two variables on exit which causes an error to occur on the next attmpt to load the driver (Benjamin Tissoires)" * tag 'acpi-extra-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / EC: Work around method reentrancy limit in ACPICA for _Qxx ACPI / button: remove pointer to old lid_sysfs on unbind

persistent_ram_zone(=prz) structures are allocated by persistent_ram_new(), which includes vmap() or ioremap(). But they are currently freed by kfree(). This uses persistent_ram_free() for correct this asymmetry usage.

Instead of a ramoops-specific node, use a child node of /reserved-memory. This requires that of_platform_device_create() be explicitly called for the node, though, since "/reserved-memory" does not have its own "compatible" property.

This script automates testing doorbells, scratchpads and memory windows for an NTB device. It can be run locally, with the NTB looped back to the same host or use SSH to remotely control the second host. In the single host case, the script just needs to be passed two arguments: a PCI ID for each side of the link. In the two host case the -r option must be used to specify the remote hostname (which must be SSH accessible and should probably have ssh-keys exchanged). A sample run looks like this: $ sudo ./ntb_test.sh 0000:03:00.1 0000:83:00.1 -p 29 Starting ntb_tool tests...

When the link goes down, the link_is_up flag did not return to false. This could have caused some subtle corner case bugs when the link goes up and down quickly. Once that was fixed, there was found to be a race if the link was brought down then immediately up. The link_cleanup work would occasionally be scheduled after the next link up event. This would cancel the link_work that was supposed to occur and leave ntb_perf in an unusable state. To fix this we get rid of the link_cleanup work and put the actions directly in the link_down event.
