From 1d1996509cd3f90551f4460a68aaf3dc940a05e3 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Tue, 4 Jun 2013 09:32:41 -0400 Subject: [PATCH] xen-blkback/sysfs: Move the parameters for the persistent grant features to a testing subdirectory (as this value should not be baked for the life-time) and also in an appropiate file. Also modified the introduction Linux version from 3.10 to 3.11.
