[PATCH v2 0/2] fix wrong value when user modify nr_request by sysfs

[weiping zhang <zhangweiping@didichuxing.com>]

Hi Jens,

This is v2 of fixing nr_request.

v1 -> v2:

blk-mq: fix nr_requests wrong value when modify it from sysfs
this patch return -EINVAL when user write a value that's too large.

blk-sysfs: return EINVAL when user modify nr_request less than
  BLKDEV_MIN_RQ
In order to keep same behavior with former patch, also return EINVAL 
when user write a value less than BLKDEV_MIN_RQ
