	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.

2018-09-26	block: Move power management code into a new source file	Bart Van Assche
	Move the code for runtime power management from blk-core.c into the new source file blk-pm.c. Move the corresponding declarations from <linux/blkdev.h> into <linux/blk-pm.h>. 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 <linux/blkdev.h> and hence should help to reduce the build time of the Linux kernel if CONFIG_PM is not defined.
