Subject: [PATCH v2 hmm 6/9] mm/hmm: use device_private_entry_to_pfn()
Date: Mon, 23 Mar 2020 22:14:54 -0300 [thread overview]
Message-ID: <20200324011457.2817-7-jgg@ziepe.ca> (raw)
In-Reply-To: <20200324011457.2817-1-jgg@ziepe.ca>
From: Jason Gunthorpe <jgg@mellanox.com>
swp_offset() should not be called directly, the wrappers are supposed to
abstract away the encoding of the device_private specific information in
the swap entry.
