From edeb69e53729342ec08a0906e1208d846a5e4f4c Mon Sep 17 00:00:00 2001 From: "Jason J. Herne" Date: Tue, 7 Oct 2014 13:31:37 -0400 Subject: [PATCH] KVM: s390: Cleanup usage of current->mm in set_guest_storage_key In set_guest_storage_key, we really want to reference the mm struct given as a parameter to the function. So replace the current->mm reference with the mm struct passed in by the caller. Signed-off-by: Jason J.
