Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2022-03-25T02:37:53+00:00

Pull SCSI updates from James Bottomley: "This series consists of the usual driver updates (qla2xxx, pm8001, libsas, smartpqi, scsi_debug, lpfc, iscsi, mpi3mr) plus minor updates and bug fixes. The high blast radius core update is the removal of write same, which affects block and several non-SCSI devices. The other big change, which is more local, is the removal of the SCSI pointer" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (281 commits) scsi: scsi_ioctl: Drop needless assignment in sg_io() scsi: bsg: Drop needless assignment in scsi_bsg_sg_io_fn() scsi: lpfc: Copyright updates for 14.2.0.0 patches scsi: lpfc: Update lpfc version to 14.2.0.0 scsi: lpfc: SLI path split: Refactor BSG paths scsi: lpfc: SLI path split: Refactor Abort paths scsi: lpfc: SLI path split: Refactor SCSI paths scsi: lpfc: SLI path split: Refactor CT paths scsi: lpfc: SLI path split: Refactor misc ELS paths scsi: lpfc: SLI path split: Refactor VMID paths scsi: lpfc: SLI path split: Refactor FDISC paths scsi: lpfc: SLI path split: Refactor LS_RJT paths scsi: lpfc: SLI path split: Refactor LS_ACC paths scsi: lpfc: SLI path split: Refactor the RSCN/SCR/RDF/EDC/FARPR paths scsi: lpfc: SLI path split: Refactor PLOGI/PRLI/ADISC/LOGO paths scsi: lpfc: SLI path split: Refactor base ELS paths and the FLOGI path scsi: lpfc: SLI path split: Introduce lpfc_prep_wqe scsi: lpfc: SLI path split: Refactor fast and slow paths to native SLI4 scsi: lpfc: SLI path split: Refactor lpfc_iocbq scsi: lpfc: Use kcalloc() ...

There are no more end-users of REQ_OP_WRITE_SAME left, so we can start deleting it. Link: https://lore.kernel.org/r/20220209082828.2629273-6-hch@lst.de Signed-off-by: Christoph Hellwig Signed-off-by: Martin K. Petersen

block: pass a block_device to bio_clone_fast

block: initialize the target bio in __bio_clone_fast

All callers of __bio_clone_fast initialize the bio first. Move that initialization into __bio_clone_fast instead. Signed-off-by: Christoph Hellwig Reviewed-by: Mike Snitzer Link: https://lore.kernel.org/r/20220202160109.108149-13-hch@lst.de Signed-off-by: Jens Axboe

block: clone crypto and integrity data in __bio_clone_fast

2022-02-04T14:43:18+00:00

__bio_clone_fast should also clone integrity and crypto data, as a clone without those is incomplete. Right now the only caller that can actually support crypto and integrity data (dm) does it manually for the one callchain that supports these, but we better do it properly in the core. Note that all callers except for the above mentioned one also don't need to handle failure at all, given that the integrity and crypto clones are based on mempool allocations that won't fail for sleeping allocations.

block: pass a block_device and opf to bio_init

2022-02-02T14:49:59+00:00

Pass the block_device that we plan to use this bio for and the operation to bio_init to optimize the assignment. A NULL block_device can be passed, both for the passthrough case on a raw request_queue and to temporarily avoid refactoring some nasty code.

md: mark some personalities as deprecated

Mark the three personalities (linear, fault and multipath) as deprecated because: 1. people can use dm multipath or nvme multipath. 2. linear is already deprecated in MODULE_ALIAS. 3. no one actively using fault. Signed-off-by: Guoqing Jiang Signed-off-by: Song Liu

writeback: remove bdi->congested_fn

2020-07-08T23:20:46+00:00

Except for pktdvd, the only places setting congested bits are file systems that allocate their own backing_dev_info structures. And pktdvd is a deprecated driver that isn't useful in stack setup either. So remove the dead congested_fn stacking infrastructure.
