Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley: "This is the final round of mostly small fixes in our initial submit. It's mostly minor fixes and driver updates. The only change of note is adding a virt_boundary_mask to the SCSI host and host template to parametrise this for NVMe devices instead of having them do a call in slave_alloc. It's a fairly straightforward conversion except in the two NVMe handling drivers that didn't set it who now have a virtual infinity parameter added" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (24 commits) scsi: megaraid_sas: set an unlimited max_segment_size scsi: mpt3sas: set an unlimited max_segment_size for SAS 3.0 HBAs scsi: IB/srp: set virt_boundary_mask in the scsi host scsi: IB/iser: set virt_boundary_mask in the scsi host scsi: storvsc: set virt_boundary_mask in the scsi host template scsi: ufshcd: set max_segment_size in the scsi host template scsi: core: take the DMA max mapping size into account scsi: core: add a host / host template field for the virt boundary scsi: core: Fix race on creating sense cache scsi: sd_zbc: Fix compilation warning scsi: libfc: fix null pointer dereference on a null lport scsi: zfcp: fix GCC compiler warning emitted with -Wmaybe-uninitialized scsi: zfcp: fix request object use-after-free in send path causing wrong traces scsi: zfcp: fix request object use-after-free in send path causing seqno errors scsi: megaraid_sas: Update driver version to 07.710.50.00 scsi: megaraid_sas: Add module parameter for FW Async event logging scsi: megaraid_sas: Enable msix_load_balance for Invader and later controllers scsi: megaraid_sas: Fix calculation of target ID scsi: lpfc: reduce stack size with CONFIG_GCC_PLUGIN_STRUCTLEAK_VERBOSE scsi: devinfo: BLIST_TRY_VPD_PAGES for SanDisk Cruzer Blade ...
