Subject: [PATCH v4 02/21] NFS: Remove unnecessary inode lock in nfs_fsync_dir()
Date: Sat,  7 Nov 2020 09:03:06 -0500	[thread overview]
Message-ID: <20201107140325.281678-3-trondmy@kernel.org> (raw)
In-Reply-To: <20201107140325.281678-2-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.
