Subject: [PATCH 5/5] s390/mm: forward check for huge pmds to pmd_large()
Date: Thu, 28 May 2015 11:52:37 +0000 [thread overview]
Message-ID: <1432813957-46874-6-git-send-email-dingel@linux.vnet.ibm.com> (raw)
In-Reply-To: <1432813957-46874-1-git-send-email-dingel@linux.vnet.ibm.com>
We already do the check in pmd_large, so we can just forward the call.
