Hello Mike,
The patches in this series are what I came up with while analyzing the
soft and hard lockups reported by Laurence Oberman. Please consider
these patches for kernel v4.14.
Thank you,
Bart.
Bart Van Assche (7):
dm: Fix the second dec_pending() argument in __split_and_process_bio()
dm: Fix printk() rate limiting code
dm-mpath: Do not lock up a CPU with requeuing activity
dm-mpath: Avoid that building with W=1 causes gcc 7 to complain about
fall-through
dm-mpath: Complain about unsupported __multipath_map_bio() return
values
dm-mpath: Retry BLK_STS_RESOURCE errors
dm-mpath: Make the dm-sq requeuing behavior consistent with the dm-mq
behavior
