Subject: [PATCH v2 tip/core/rcu 0/10] Remove spin_unlock_wait()
Date: Mon, 31 Jul 2017 15:57:54 -0700 [thread overview]
Message-ID: <20170731225754.GB2674@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170724221252.GA14238@linux.vnet.ibm.com>
Hello!
This series removes spin_unlock_wait():
1. Revert over-enthusiastic spin_unlock_wait() header comment.
2. Remove spin_unlock_wait() from net/netfilter/nf_conntrack_core,
courtesy of Manfred Spraul.
3. Replace task_work use of spin_unlock_wait() with lock/unlock
pair, courtesy of Oleg Nesterov.
4. Replace scheduler use of spin_unlock_wait() with lock/unlock pair.
5. Replace completion use of spin_unlock_wait() with lock/unlock
pair.
6. Replace exit() use of spin_unlock_wait() with lock/unlock pair.
7. Replace IPC use of spin_unlock_wait() with lock/unlock pair.
8. Replace ATA use of spin_unlock_wait() with lock/unlock pair.
9. Remove generic definition of spin_unlock_wait().
10. Remove architecture-specific definitions of spin_unlock_wait().
Thanx, Paul
