block: remove the queue_lock indirection

2018-11-15T19:17:28+00:00

With the legacy request path gone there is no good reason to keep queue_lock as a pointer, we can always use the embedded lock now. Reviewed-by: Hannes Reinecke Signed-off-by: Christoph Hellwig Fixed floppy and blk-cgroup missing conversions and half done edits. Signed-off-by: Jens Axboe

block: Split blk_pm_add_request() and blk_pm_put_request()

2018-09-26T21:11:28+00:00

Move the pm_request_resume() and pm_runtime_mark_last_busy() calls into two new functions and thereby separate legacy block layer code from code that works for both the legacy block layer and blk-mq. A later patch will add calls to the new functions in the blk-mq code. Signed-off-by: Bart Van Assche Reviewed-by: Ming Lei Reviewed-by: Christoph Hellwig Cc: Martin K.

block: Move power management code into a new source file

2018-09-26T21:11:28+00:00

Move the code for runtime power management from blk-core.c into the new source file blk-pm.c. Move the corresponding declarations from into . For CONFIG_PM=n, leave out the declarations of the functions that are not used in that mode. This patch not only reduces the number of #ifdefs in the block layer core code but also reduces the size of header file and hence should help to reduce the build time of the Linux kernel if CONFIG_PM is not defined.
