Merge tag 'drivers-5.10-2020-10-12' of git://git.kernel.dk/linux-blockjd/orphan-parallel
Pull block driver updates from Jens Axboe: "Here are the driver updates for 5.10. A few SCSI updates in here too, in coordination with Martin as they depend on core block changes for the shared tag bitmap. This contains: - NVMe pull requests via Christoph: - fix keep alive timer modification (Amit Engel) - order the PCI ID list more sensibly (Andy Shevchenko) - cleanup the open by controller helper (Chaitanya Kulkarni) - use an xarray for the CSE log lookup (Chaitanya Kulkarni) - support ZNS in nvmet passthrough mode (Chaitanya Kulkarni) - fix nvme_ns_report_zones (Christoph Hellwig) - add a sanity check to nvmet-fc (James Smart) - fix interrupt allocation when too many polled queues are specified (Jeffle Xu) - small nvmet-tcp optimization (Mark Wunderlich) - fix a controller refcount leak on init failure (Chaitanya Kulkarni) - misc cleanups (Chaitanya Kulkarni) - major refactoring of the scanning code (Christoph Hellwig) - MD updates via Song: - Bug fixes in bitmap code, from Zhao Heming - Fix a work queue check, from Guoqing Jiang - Fix raid5 oops with reshape, from Song Liu - Clean up unused code, from Jason Yan - Discard improvements, from Xiao Ni - raid5/6 page offset support, from Yufen Yu - Shared tag bitmap for SCSI/hisi_sas/null_blk (John, Kashyap, Hannes) - null_blk open/active zone limit support (Niklas) - Set of bcache updates (Coly, Dongsheng, Qinglang)" * tag 'drivers-5.10-2020-10-12' of git://git.kernel.dk/linux-block: (78 commits) md/raid5: fix oops during stripe resizing md/bitmap: fix memory leak of temporary bitmap md: fix the checking of wrong work queue md/bitmap: md_bitmap_get_counter returns wrong blocks md/bitmap: md_bitmap_read_sb uses wrong bitmap blocks md/raid0: remove unused function is_io_in_chunk_boundary() nvme-core: remove extra condition for vwc nvme-core: remove extra variable nvme: remove nvme_identify_ns_list nvme: refactor nvme_validate_ns nvme: move nvme_validate_ns nvme: query namespace identifiers before adding the namespace nvme: revalidate zone bitmaps in nvme_update_ns_info nvme: remove nvme_update_formats nvme: update the known admin effects nvme: set the queue limits in nvme_update_ns_info nvme: remove the 0 lba_shift check in nvme_update_ns_info nvme: clean up the check for too large logic block sizes nvme: freeze the queue over ->lba_shift updates nvme: factor out a nvme_configure_metadata helper ...
