From 9691a071aa26a21fc8dac804a2b98d3c24f76f9a Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Wed, 3 Jun 2020 15:57:10 -0700 Subject: [PATCH] mm: use free_area_init() instead of free_area_init_nodes() free_area_init() has effectively became a wrapper for free_area_init_nodes() and there is no point of keeping it. Still free_area_init() name is shorter and more general as it does not imply necessity to initialize multiple nodes. Rename free_area_init_nodes() to free_area_init(), update the callers and drop old version of free_area_init().
