Hi Linus,
A smaller collection of fixes that should go into -rc1. This pull
request contains:
- A fix from Christoph, fixing a regression with the WRITE_SAME
and partial completions. Caused a BUG() on ppc.
- Fixup for __blk_mq_stop_hw_queues(), it should be static. From Colin.
- Removal of dmesg error messages on elevator switching, when invoked
from sysfs. From me.
- Fix for blk-stat, using this_cpu_ptr() in a section only protected by
rcu_read_lock(). This breaks when PREEMPT_RCU is enabled. From me.
- Two fixes for BFQ from Paolo, one fixing a crash and one updating the
documentation.
- An error handling lightnvm memory leak, from Rakesh.
- The previous blk-mq hot unplug lock reversal depends on the CPU
hotplug rework that isn't in mainline yet. This caused a lockdep splat
when people unplugged CPUs with blk-mq devices. From Wanpeng.
- A regression fix for DIF/DIX on blk-mq. From Wen.
Please pull!
