From 4c6cd03ed88cbeed796d840a4f9c8ac082e82409 Mon Sep 17 00:00:00 2001 From: Barry Song Date: Tue, 13 Oct 2020 16:51:51 -0700 Subject: mm/gup_benchmark: update the documentation in Kconfig In the beginning, mm/gup_benchmark.c supported get_user_pages_fast() only, but right now, it supports the benchmarking of a couple of get_user_pages() related calls like: * get_user_pages_fast() * get_user_pages() * pin_user_pages_fast() * pin_user_pages() The documentation is confusing and needs update.
