Subject: [PATCH v2 1/4] dax: kill uml support
Date: Thu, 22 Dec 2016 14:18:53 -0700 [thread overview]
Message-ID: <1482441536-14550-2-git-send-email-ross.zwisler@linux.intel.com> (raw)
In-Reply-To: <1482441536-14550-1-git-send-email-ross.zwisler@linux.intel.com>
From: Dan Williams <dan.j.williams@intel.com>
The lack of common transparent-huge-page helpers for UML is becoming
increasingly painful for fs/dax.c now that it is growing more pmd
functionality. Add UML to the list of unsupported architectures.
