From 25f12ae45fc1931a1dce3cc59f9989a9d87834b0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 17 Jun 2020 09:37:55 +0200 Subject: maccess: rename probe_kernel_address to get_kernel_nofault Better describe what this helper does, and match the naming of copy_from_kernel_nofault. Also switch the argument order around, so that it acts and looks like get_user().
