block: simplify queue allocation

2020-03-27T16:23:43Z

Current make_request based drivers use either blk_alloc_queue_node or blk_alloc_queue to allocate a queue, and then set up the make_request_fn function pointer and a few parameters using the blk_queue_make_request helper. Simplify this by passing the make_request pointer to blk_alloc_queue, and while at it merge the _node variant into the main helper by always passing a node_id, and remove the superfluous gfp_mask parameter. A lower-level __blk_alloc_queue is kept for the blk-mq case. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

block: move the part_stat* helpers from genhd.h to a new header

2020-03-25T15:50:09Z

These macros are just used by a few files. Move them out of genhd.h, which is included everywhere into a new standalone header. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

block/drbd: delete invalid function drbd_md_mark_dirty_

2020-03-12T13:49:09Z

We deleted last_md_mark_dirty long ago, this function no longer needs to exist, delete it, otherwise a compilation error will occur when DEBUG is opened. Fixes: ac0acb9e39ac ("drbd: use drbd_device_post_work() in more place") Signed-off-by: Jackie Liu Signed-off-by: Jens Axboe

drbd: fifo_alloc() should use struct_size

2020-01-30T04:03:33Z

Switching to struct_size for the allocation in fifo_alloc avoids hard-coding the type of fifo_buffer.values in fifo_alloc. It also provides overflow protection; to avoid pessimistic code being generated by the compiler as a result, this patch also switches fifo_size to unsigned, propagating the change as appropriate.

block: drbd: remove a stray unlock in __drbd_send_protocol()

2019-11-08T13:55:22Z

There are two callers of this function and they both unlock the mutex so this ends up being a double unlock. Fixes: 44ed167da748 ("drbd: rcu_read_lock() and rcu_dereference() for tconn->net_conf") Signed-off-by: Dan Carpenter Signed-off-by: Jens Axboe

drbd: Use pr_warn instead of pr_warning

2019-10-18T13:00:19Z

As said in commit f2c2cbcc35d4 ("powerpc: Use pr_warn instead of pr_warning"), removing pr_warning so all logging messages use a consistent _warn style. Let's do it.

augmented rbtree: add new RB_DECLARE_CALLBACKS_MAX macro

2019-09-26T00:51:39Z

Add RB_DECLARE_CALLBACKS_MAX, which generates augmented rbtree callbacks for the case where the augmented value is a scalar whose definition follows a max(f(node)) pattern. This actually covers all present uses of RB_DECLARE_CALLBACKS, and saves some (source) code duplication in the various RBCOMPUTE function definitions.
