[PATCH 0/2] fix crash by reading /proc/diskstats

[Daniel Wagner]

During failover nvme-tcp tests in a HA setup a crash orccured. iostat
was running in the background while the test was executed.

I am not sure if the fix is correct. I am unsure if using
blk_queue_enter() is the right thing. But when starring at the code
snipped I saw in older version blk_queue_enter() was used but got
evenutally replaced by the rcu_read_lock() as far I understand at the
moment... So any tip here would be highly appreciated.
