Subject: [PATCH RFC 17/26] metag: Remove spin_unlock_wait() arch-specific definitions
Date: Thu, 29 Jun 2017 17:01:25 -0700 [thread overview]
Message-ID: <1498780894-8253-17-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170629235918.GA6445@linux.vnet.ibm.com>
There is no agreed-upon definition of spin_unlock_wait()'s semantics,
and it appears that all callers could do just as well with a lock/unlock
pair. This commit therefore removes the underlying arch-specific
arch_spin_unlock_wait().
