From 44788591c3cfb81d9315b8ee5c2076e51bfe8a39 Mon Sep 17 00:00:00 2001 From: Ira Weiny Date: Tue, 25 May 2021 10:24:27 -0700 Subject: fs/dax: Clarify nr_pages to dax_direct_access() dax_direct_access() takes a number of pages. PHYS_PFN(PAGE_SIZE) is a very round about way to specify '1'. Change the nr_pages parameter to the explicit value of '1'.
