Subject: [PATCH v5 02/22] NFS: Remove unnecessary inode lock in nfs_fsync_dir()
Date: Tue, 10 Nov 2020 16:37:21 -0500	[thread overview]
Message-ID: <20201110213741.860745-3-trondmy@kernel.org> (raw)
In-Reply-To: <20201110213741.860745-2-trondmy@kernel.org>

From: Trond Myklebust <trond.myklebust@hammerspace.com>

nfs_inc_stats() is already thread-safe, and there are no other reasons
to hold the inode lock here.
