From b02739b01c5309d74a59859f2ce92c931d1f1955 Mon Sep 17 00:00:00 2001 From: "Martin K. Petersen" Date: Thu, 2 Oct 2008 18:47:49 +0200 Subject: [PATCH] block: gendisk integrity wrapper This is a wrapper for accessing a gendisk's integrity bits. It allows the integrity support in MD to be compiled with BLK_DEV_INTEGRITY off. Signed-off-by: Martin K.
