Merge branch 'for-4.12/post-merge' of git://git.kernel.dk/linux-block
Pull second round of block layer updates from Jens Axboe: - Further fixups to the NVMe APST code, from Andy. - Various fixes for (mostly) nvme-fc, from Christoph and James. - NVMe scsi fixes from Jon and Christoph. * 'for-4.12/post-merge' of git://git.kernel.dk/linux-block: (39 commits) nvme-scsi: remove nvme_trans_security_protocol nvme-lightnvm: add missing endianess conversion in nvme_nvm_end_io nvme-scsi: Consider LBA format in IO splitting calculation nvme-fc: avoid memory corruption caused by calling nvmf_free_options() twice lpfc: Fix memory corruption of the lpfc_ncmd->list pointers nvme: Add nvme_core.force_apst to ignore the NO_APST quirk nvme: Display raw APST configuration via DYNAMIC_DEBUG nvme: Fix APST comment lpfc revison 11.2.0.12 Fix Express lane queue creation. Update ABORT processing for NVMET. Fix implicit logo and RSCN handling for NVMET Add Fabric assigned WWN support. Fix max_sgl_segments settings for NVME / NVMET Fix crash after issuing lip reset Fix driver load issues when MRQ=8 Remove hba lock from NVMET issue WQE. Fix nvme initiator handling when not enabled. Fix driver usage of 128B WQEs when WQ_CREATE is V1. Fix driver unload/reload operation. ...
