Subject: [PATCH 0/2] block: remove retry loop
Date: Fri, 19 Jun 2020 17:23:16 +0206 [thread overview]
Message-ID: <20200619151718.22338-1-john.ogness@linutronix.de> (raw)
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()
