From 2b9059489c839e67ca9254913325e18cea11a980 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 1 Jun 2020 21:51:53 -0700 Subject: [PATCH] mm: remove __vmalloc_node_flags_caller Just use __vmalloc_node instead which gets and extra argument. To be able to to use __vmalloc_node in all caller make it available outside of vmalloc and implement it in nommu.c.
