2020-06-03RDMA/cm: Spurious WARNING triggered in cm_destroy_id()Ka-Cheong Poon
If the cm_id state is IB_CM_REP_SENT when cm_destroy_id() is called, it calls cm_send_rej_locked(). In cm_send_rej_locked(), it calls cm_enter_timewait() and the state is changed to IB_CM_TIMEWAIT. Now back to cm_destroy_id(), it breaks from the switch statement, and the next call is WARN_ON(cm_id->state != IB_CM_IDLE). This triggers a spurious warning. Instead, the code should goto retest after returning from cm_send_rej_locked() to move the state to IDLE.

2020-06-03RDMA/mlx5: Return ECE DC supportLeon Romanovsky
The DC QPs are many-to-one QP types that means that first connection will establish ECE options that coming connections should follow. Due to this property, the ECE code was removed between first [1] and second [2] ECE submissions. This patch returns the dropped code, because ECE is a property of a connection and like any other connection users are needed to manage this data. Allow them to set ECE parameter for DC too and avoid need of having compatibility flag for the DC ECE.

2020-06-03gpio: add a reusable generic gpio_chip using regmapMichael Walle
There are quite a lot simple GPIO controller which are using regmap to access the hardware. This driver tries to be a base to unify existing code into one place. This won't cover everything but it should be a good starting point. It does not implement its own irq_chip because there is already a generic one for regmap based devices. Instead, the irq_chip will be instantiated in the parent driver and its irq domain will be associate to this driver. For now it consists of the usual registers, like set (and an optional clear) data register, an input register and direction registers. Out-of-the-box, it supports consecutive register mappings and mappings where the registers have gaps between them with a linear mapping between GPIO offset and bit position. For weirder mappings the user can register its own .xlate().

Pull DAX updates part one from Darrick Wong: "After many years of LKML-wrangling about how to enable programs to query and influence the file data access mode (DAX) when a filesystem resides on storage devices such as persistent memory, Ira Weiny has emerged with a proposed set of standard behaviors that has not been shot down by anyone! We're more or less standardizing on the current XFS behavior and adapting ext4 to do the same. This is the first of a handful pull requests that will make ext4 and XFS present a consistent interface for user programs that care about DAX. We add a statx attribute that programs can check to see if DAX is enabled on a particular file. Then, we update the DAX documentation to spell out the user-visible behaviors that filesystems will guarantee (until the next storage industry shakeup). The on-disk inode flag has been in XFS for a few years now. Summary: - Clean up io_is_direct. - Add a new statx flag to indicate when file data access is being done via DAX (as opposed to the page cache). - Update the documentation for how system administrators and application programmers can take advantage of the (still experimental DAX) feature" Link: https://lore.kernel.org/lkml/20200505002016.1085071-1-ira.weiny@intel.com/ * tag 'vfs-5.8-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: Documentation/dax: Update Usage section fs/stat: Define DAX statx attribute fs: Remove unneeded IS_DAX() check in io_is_direct()

2020-06-02ubi: Select fastmap anchor PEBs considering wear level rulesArne Edholm
There is a risk that the fastmap anchor PEB is alternating between just two PEBs, the current anchor and the previous anchor that was just deleted. As the fastmap pools gets the first take on free PEBs, the pools may leave no free PEBs to be selected as the new anchor, resulting in the two PEBs alternating behaviour. If the anchor PEBs gets a high erase count the PEBs will not be used by the pools but remain in ubi->free, even more increasing the likelihood they will be used as anchors. Getting stuck using only a couple of PEBs continuously will result in an uneven wear, eventually leading to failure. To fix this: - Choose the fastmap anchor when the most free PEBs are available. This is during rebuilding of the fastmap pools, after the unused pool PEBs are added to ubi->free but before the pools are populated again from the free PEBs. Also reserve an additional second best PEB as a candidate for the next time the fast map anchor is updated. If a better PEB is found the next time the fast map anchor is updated, the candidate is made available for building the pools. - Enable anchor move within the anchor area again as it is useful for distributing wear. - The anchor candidate for the next fastmap update is the most suited free PEB. Check this PEB's erase count during wear leveling. If the wear leveling limit is exceeded, the PEB is considered unsuitable for now. As all other non used anchor area PEBs should be even worse, free up the used anchor area PEB with the lowest erase count.
