From f66c9a33aee943aa43b3698c1f6f2619e28a1c77 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Fri, 27 Mar 2020 17:00:18 -0300 Subject: [PATCH] mm/hmm: use device_private_entry_to_pfn() 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.
