blk-mq: pass a flags argument to elevator_type->insert_requests Instead of passing a bool at_head, pass down the full flags from the blk_mq_insert_request interface.

block: add proper helpers for elevator_type module refcount management Make sure we have helpers for all relevant module refcount operations on the elevator_type in elevator.h, and use them. Move the call to the get helper in blk_mq_elv_switch_none a bit so that it is obvious with a less verbose comment.

blk-wbt: don't enable throttling if default elevator is bfq Commit b5dc5d4d1f4f ("block,bfq: Disable writeback throttling") tries to disable wbt for bfq, it's done by calling wbt_disable_default() in bfq_init_queue(). However, wbt is still enabled if default elevator is bfq: device_add_disk elevator_init_mq bfq_init_queue wbt_disable_default -> done nothing blk_register_queue wbt_enable_default -> wbt is enabled Fix the problem by adding a new flag ELEVATOR_FLAG_DISBALE_WBT, bfq will set the flag in bfq_init_queue, and following wbt_enable_default() won't enable wbt while the flag is set.

block: Use the new blk_opf_t type Use the new blk_opf_t type for arguments and variables that represent request flags or a bitwise combination of a request operation and request flags. Rename the function arguments and also a structure member that hold a request operation and flags from 'rw' into 'opf'. This patch does not change any functionality.

block: move elevator.h to block/ Except for the features passed to blk_queue_required_elevator_features, elevator.h is only needed internally to the block layer. Move the ELEVATOR_F_* definitions to blkdev.h, and the move elevator.h to block/, dropping all the spurious includes outside of that.
