Subject: [PATCH V2 6/7] IB/qib: Use the new FOLL_LONGTERM flag to get_user_pages_fast()
Date: Wed, 13 Feb 2019 15:04:54 -0800 [thread overview]
Message-ID: <20190213230455.5605-7-ira.weiny@intel.com> (raw)
In-Reply-To: <20190213230455.5605-1-ira.weiny@intel.com>
From: Ira Weiny <ira.weiny@intel.com>
Use the new FOLL_LONGTERM to get_user_pages_fast() to protect against
FS DAX pages being mapped.
