commit 5a97806f7dc069d9561d9930a2ae108700e222ab
|
|
Author: Christoph Hellwig <hch@lst.de>

|
|
block: change the blk_queue_split calling convention
|
|
|
|
The double indirect bio leads to somewhat suboptimal code generation.
|
|
Instead return the (original or split) bio, and make sure the
|
|
request_queue arguments to the lower level helpers is passed after the
|
|
bio to avoid constant reshuffling of the argument passing registers.
|
|
|
|
Also give it and the helpers used to implement it more descriptive names.
