Subject: [PATCH 12/12] vfat: don't use ->d_time
Date: Fri, 16 Sep 2016 14:19:31 +0200 [thread overview]
Message-ID: <1474028371-21288-13-git-send-email-mszeredi@redhat.com> (raw)
In-Reply-To: <1474028371-21288-1-git-send-email-mszeredi@redhat.com>
Use d_fsdata instead, which is the same size. Introduce helpers to hide
the typecasts.
