From 7ae12a57c56e0b87e6e698479c1f8b65434a608f Mon Sep 17 00:00:00 2001 From: Hongbo Li Date: Wed, 28 Aug 2024 12:12:16 +0800 Subject: [PATCH] mm/vmalloc.c: make use of the helper macro LIST_HEAD() list_head can be initialized automatically with LIST_HEAD() instead of calling INIT_LIST_HEAD(). Here we can simplify the code.
