Subject: [PATCH v2 23/26] NFSv4: nfs4_inc/dec_nlink_locked should also invalidate ctime
Date: Wed, 14 Apr 2021 09:43:50 -0400	[thread overview]
Message-ID: <20210414134353.11860-24-trondmy@kernel.org> (raw)
In-Reply-To: <20210414134353.11860-23-trondmy@kernel.org>

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

If the nlink changes, then so will the ctime.
