[PATCH 05/19] fs: Add super_operations

From: Sascha Hauer <s.hauer@pengutronix.de>

Subject: [PATCH 05/19] fs: Add super_operations
Date: Tue,  3 Apr 2018 09:48:37 +0200	[thread overview]
Message-ID: <20180403074851.5411-6-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20180403074851.5411-1-s.hauer@pengutronix.de>

Add a struct super_operations we can use later when we get a fs
implementation closer to Linux. Only add the functions we'll likely
need though.
