Subject: [PATCH -next] nfsd: use DEFINE_SPINLOCK() for spinlock
Date: Sat, 25 Jul 2020 16:56:42 +0800 [thread overview]
Message-ID: <20200725085642.98356-1-miaoqinglang@huawei.com> (raw)
nfsd_drc_lock can be initialized automatically with
DEFINE_SPINLOCK() rather than explicitly calling spin_lock_init().
