Subject: [PATCH 02/26] fscrypto: Constify struct inode pointer
Date: Fri, 21 Oct 2016 14:48:17 +0200 [thread overview]
Message-ID: <1477054121-10198-3-git-send-email-richard@nod.at> (raw)
In-Reply-To: <1477054121-10198-1-git-send-email-richard@nod.at>
Some filesystems, such as UBIFS, maintain a const pointer
for struct inode.
