From 67a929e097b774c69253c8b61ef9eb8a42b463a3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig <hch@lst.de> Date: Thu, 11 Jul 2019 20:57:14 -0700 Subject: [PATCH] mm: rename CONFIG_HAVE_GENERIC_GUP to CONFIG_HAVE_FAST_GUP We only support the generic GUP now, so rename the config option to be more clear, and always use the mm/Kconfig definition of the symbol and select it from the arch Kconfigs.
