From f1c4069e1dc128dc8a851174cba2e273652e9216 Mon Sep 17 00:00:00 2001 From: Joonsoo Kim Date: Mon, 29 Apr 2013 15:07:37 -0700 Subject: mm, vmalloc: export vmap_area_list, instead of vmlist Although our intention is to unexport internal structure entirely, but there is one exception for kexec. kexec dumps address of vmlist and makedumpfile uses this information. We are about to remove vmlist, then another way to retrieve information of vmalloc layer is needed for makedumpfile. For this purpose, we export vmap_area_list, instead of vmlist.
