Merge tag 'for-4.13/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper fixes from Mike Snitzer:
- A couple fixes for bugs introduced as part of the blk_status_t block
layer changes during the 4.13 merge window
- A printk throttling fix to use discrete rate limiting state for each
DM log level
- A stable@ fix for DM multipath that delays request requeueing to
avoid CPU lockup if/when the request queue is "dying"
* tag 'for-4.13/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
dm mpath: do not lock up a CPU with requeuing activity
dm: fix printk() rate limiting code
dm mpath: retry BLK_STS_RESOURCE errors
dm: fix the second dec_pending() argument in __split_and_process_bio()
