Pull block driver updates from Jens Axboe: "Nothing major in here: - NVMe pull request from Christoph: - nvmet passthrough improvements (Chaitanya Kulkarni) - fcloop error injection support (James Smart) - read-only support for zoned namespaces without Zone Append (Javier González) - improve some error message (Minwoo Im) - reject I/O to offline fabrics namespaces (Victor Gladkov) - PCI queue allocation cleanups (Niklas Schnelle) - remove an unused allocation in nvmet (Amit Engel) - a Kconfig spelling fix (Colin Ian King) - nvme_req_qid simplication (Baolin Wang) - MD pull request from Song: - Fix race condition in md_ioctl() (Dae R. Jeong) - Initialize read_slot properly for raid10 (Kevin Vigor) - Code cleanup (Pankaj Gupta) - md-cluster resync/reshape fix (Zhao Heming) - Move null_blk into its own directory (Damien Le Moal) - null_blk zone and discard improvements (Damien Le Moal) - bcache race fix (Dongsheng Yang) - Set of rnbd fixes/improvements (Gioh Kim, Guoqing Jiang, Jack Wang, Lutz Pogrell, Md Haris Iqbal) - lightnvm NULL pointer deref fix (tangzhenhao) - sr in_interrupt() removal (Sebastian Andrzej Siewior) - FC endpoint security support for s390/dasd (Jan Höppner, Sebastian Ott, Vineeth Vijayan). From the s390 arch guys, arch bits included as it made it easier for them to funnel the feature through the block driver tree. - Follow up fixes (Colin Ian King)" * tag 'for-5.11/drivers-2020-12-14' of git://git.kernel.dk/linux-block: (64 commits) block: drop dead assignments in loop_init() sr: Remove in_interrupt() usage in sr_init_command(). sr: Switch the sector size back to 2048 if sr_read_sector() changed it. cdrom: Reset sector_size back it is not 2048. drivers/lightnvm: fix a null-ptr-deref bug in pblk-core.c null_blk: Move driver into its own directory null_blk: Allow controlling max_hw_sectors limit null_blk: discard zones on reset null_blk: cleanup discard handling null_blk: Improve implicit zone close null_blk: improve zone locking block: Align max_hw_sectors to logical blocksize null_blk: Fail zone append to conventional zones null_blk: Fix zone size initialization bcache: fix race between setting bdev state to none and new write request direct to backing block/rnbd: fix a null pointer dereference on dev->blk_symlink_name block/rnbd-clt: Dynamically alloc buffer for pathname & blk_symlink_name block/rnbd: call kobject_put in the failure path Documentation/ABI/rnbd-srv: add document for force_close block/rnbd-srv: close a mapped device from server side. ...
