Subject: [PATCH RFC 7/8] NFSD: Clean up nfsd_open_verified()
Date: Wed, 20 Apr 2022 14:29:19 -0400	[thread overview]
Message-ID: <165047935951.1829.4140838884832238133.stgit@manet.1015granger.net> (raw)
In-Reply-To: <165047903719.1829.18357114060053600197.stgit@manet.1015granger.net>

Its only caller always passes S_IFREG as the @type parameter. As an
additional clean-up, add a kerneldoc comment.
