[PATCH bpf-next v5 2/7] security: Refactor declaration of LSM hooks

KP Singh
2020-03-23T16:44:40Z

From: KP Singh <kpsingh@google.com>

The information about the different types of LSM hooks is scattered
in two locations i.e. union security_list_options and
struct security_hook_heads. Rather than duplicating this information
even further for BPF_PROG_TYPE_LSM, define all the hooks with the
LSM_HOOK macro in lsm_hook_names.h which is then used to generate all
the data structures required by the LSM framework.
