From 5248ee85603067e62a228402afd2fb68f957746b Mon Sep 17 00:00:00 2001 From: Zubin Mithra Date: Wed, 25 Jul 2018 10:19:01 -0700 Subject: tracefs: Annotate tracefs_ops with __ro_after_init tracefs_ops is initialized inside tracefs_create_instance_dir and not modified after. tracefs_create_instance_dir allows for initialization only once, and is called from create_trace_instances(marked __init), which is called from tracer_init_tracefs(marked __init). Also, mark tracefs_create_instance_dir as __init.
