*	block: use __this_cpu_add() instead of access by smp_processor_id()	Konstantin Khlebnikov	2020-05-27	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \|	Most architectures have fast path to access percpu for current cpu. The required preempt_disable() is provided by part_stat_lock().

*	block: remove rcu_read_lock() from part_stat_lock()	Konstantin Khlebnikov	2020-05-27	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \|	The RCU lock is required only in disk_map_sector_rcu() to lookup the partition. After that request holds reference to related hd_struct. Replace get_cpu() with preempt_disable() - returned cpu index is unused.

*	block: always use a percpu variable for disk stats	Christoph Hellwig	2020-05-27	1	-44/+11
\| \| \| \| \| \| \| \| \|	percpu variables have a perfectly fine working stub implementation for UP kernels, so use that. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Konstantin Khlebnikov <khlebnikov@yandex-team.ru> Signed-off-by: Jens Axboe <axboe@kernel.dk>
*	block: move the part_stat* helpers from genhd.h to a new header	Christoph Hellwig	2020-03-25	1	-0/+115
	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 <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
