Subject: [GIT PULL 2/9] KVM: s390: Cleanup usage of current->mm in set_guest_storage_key
Date: Tue, 28 Oct 2014 20:39:52 +0100 [thread overview]
Message-ID: <1414525199-53989-3-git-send-email-borntraeger@de.ibm.com> (raw)
In-Reply-To: <1414525199-53989-1-git-send-email-borntraeger@de.ibm.com>
From: "Jason J. Herne" <jjherne@us.ibm.com>
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.
