From 4ad0ae8c64ac8f81a3651bca11be7c3cb086df80 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Thu, 29 Apr 2021 22:59:01 -0700 Subject: mm/vmalloc: remove unmap_kernel_range MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a shim around vunmap_range, get rid of it. Move the main API comment from the _noflush variant to the normal variant, and make _noflush internal to mm/.
