From 3539b96e041c06e4317082816d90ec09160aeb11 Mon Sep 17 00:00:00 2001 From: Roman Gushchin Date: Wed, 29 May 2019 18:03:57 -0700 Subject: bpf: group memory related fields in struct bpf_map_memory Group "user" and "pages" fields of bpf_map into the bpf_map_memory structure. Later it can be extended with "memcg" and other related information. The main reason for a such change (beside cosmetics) is to pass bpf_map_memory structure to charging functions before the actual allocation of bpf_map.
