Subject: [PATCH 0/2] block: remove retry loop

Hello,

This series removes a retry loop in the ioc reverse-order
double lock dance, replacing it with an implementation that
uses guaranteed forward progress.

While at it, it also removes the nested spinlock usage,
which no longer applies since CFQ is gone.

John Ogness (2):
  block: remove unnecessary ioc nested locking
  block: remove retry loop in ioc_release_fn()
