From 73cf09a36bf7bfb3e5a3ff23755c36d49137c44d Mon Sep 17 00:00:00 2001 From: Yafang Shao Date: Wed, 10 Aug 2022 15:18:29 +0000 Subject: bpf: Use bpf_map_area_alloc consistently on bpf map creation Let's use the generic helper bpf_map_area_alloc() instead of the open-coded kzalloc helpers in bpf maps creation path.
