Subject: [PATCH 3/7] fs/adfs: factor out object fixups
Date: Mon, 20 May 2019 15:13:13 +0100 [thread overview]
Message-ID: <E1hSj2P-0000LW-RM@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20190520141227.krqowhs3yg7hpige@shell.armlinux.org.uk>
Factor out the directory object fixups, which parse the filetype and
optionally apply the filetype suffix to the filename.
