nvmet: release the sq ref on rdma read errors

2017-05-20T16:11:34Z

On rdma read errors, release the sq ref that was taken when the req was initialized. This avoids a hang in nvmet_sq_destroy() when the queue is being freed. Signed-off-by: Vijay Immanuel Reviewed-by: Sagi Grimberg Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

nvmet: Introduced helper routine for controller status check.

2017-04-04T15:48:23Z

This patch introduces helper function for checking controller status during admin and io command processing which returns u16 status. As to bring consistency on returning status, other friend functions also now return u16 status instead of int to match the spec. As part of the theseerror log prints in also prints qid on which command error occured.

nvmet: confirm sq percpu has scheduled and switched to atomic

2017-04-04T15:48:23Z

percpu_ref_kill is not enough to prevent subsequent percpu_ref_tryget_live from failing. Hence call perfcpu_ref_kill_confirm to make it safe. Reviewed-by: Christoph Hellwig Signed-off-by: Sagi Grimberg Signed-off-by: Jens Axboe

sched/headers: Prepare to use instead of in

2017-03-02T07:42:38Z

We don't actually need the full rculist.h header in sched.h anymore, we will be able to include the smaller rcupdate.h header instead. But first update code that relied on the implicit header inclusion.

nvmet: Make cntlid globally unique

2017-02-22T20:34:00Z

We usually log the cntlid which is confusing in case we have multiple subsystems each with it's own cntlid ida. Instead make cntlid ida globally unique and log the initial association.

nvmet: Call fatal_error from keep-alive timout expiration

2017-01-26T15:45:03Z

We only need to call delete_ctrl once, so given that both keep-alive timeout and any other fatal error can trigger it, just make sure we only call delete_ctrl once. Signed-off-by: Sagi Grimberg Reviewed-by: Christoph Hellwig

nvmet: cancel fatal error and flush async work before free controller

Make sure they are not running and we can free the controller safely. Signed-off-by: Roy Shterman Signed-off-by: Sagi Grimberg Reviewed-by: Christoph Hellwig

nvmet: delete controllers deletion upon subsystem release

2017-01-26T15:44:22Z

No reason for them to be kept around if we are deleting the subsystem, so instead of passively wait for the host to disconnect, actively delete the controllers. Signed-off-by: Sagi Grimberg Reviewed-by: Johannes Thumshirn Reviewed-by: Max Gurtovoy Reviewed-by: Christoph Hellwig

Merge branch 'for-4.10/block' of git://git.kernel.dk/linux-block

2016-12-13T18:19:16Z

Pull block layer updates from Jens Axboe: "This is the main block pull request this series. Contrary to previous release, I've kept the core and driver changes in the same branch. We always ended up having dependencies between the two for obvious reasons, so makes more sense to keep them together. That said, I'll probably try and keep more topical branches going forward, especially for cycles that end up being as busy as this one. The major parts of this pull request is: - Improved support for O_DIRECT on block devices, with a small private implementation instead of using the pig that is fs/direct-io.c. From Christoph. - Request completion tracking in a scalable fashion. This is utilized by two components in this pull, the new hybrid polling and the writeback queue throttling code. - Improved support for polling with O_DIRECT, adding a hybrid mode that combines pure polling with an initial sleep. From me. - Support for automatic throttling of writeback queues on the block side. This uses feedback from the device completion latencies to scale the queue on the block side up or down. From me. - Support from SMR drives in the block layer and for SD. From Hannes and Shaun. - Multi-connection support for nbd. From Josef. - Cleanup of request and bio flags, so we have a clear split between which are bio (or rq) private, and which ones are shared. From Christoph. - A set of patches from Bart, that improve how we handle queue stopping and starting in blk-mq. - Support for WRITE_ZEROES from Chaitanya. - Lightnvm updates from Javier/Matias. - Supoort for FC for the nvme-over-fabrics code. From James Smart. - A bunch of fixes from a whole slew of people, too many to name here" * 'for-4.10/block' of git://git.kernel.dk/linux-block: (182 commits) blk-stat: fix a few cases of missing batch flushing blk-flush: run the queue when inserting blk-mq flush elevator: make the rqhash helpers exported blk-mq: abstract out blk_mq_dispatch_rq_list() helper blk-mq: add blk_mq_start_stopped_hw_queue() block: improve handling of the magic discard payload blk-wbt: don't throttle discard or write zeroes nbd: use dev_err_ratelimited in io path nbd: reset the setup task for NBD_CLEAR_SOCK nvme-fabrics: Add FC LLDD loopback driver to test FC-NVME nvme-fabrics: Add target support for FC transport nvme-fabrics: Add host support for FC transport nvme-fabrics: Add FC transport LLDD api definitions nvme-fabrics: Add FC transport FC-NVME definitions nvme-fabrics: Add FC transport error codes to nvme.h Add type 0x28 NVME type code to scsi fc headers nvme-fabrics: patch target code in prep for FC transport support nvme-fabrics: set sqe.command_id in core not transports parser: add u64 number parser nvme-rdma: align to generic ib_event logging helper ...
