tracing: Annotate event field-defining functions with __init
Those functions are called either during kernel boot or module init. Before: $ dmesg | grep 'Freeing unused kernel memory' Freeing unused kernel memory: 1208k freed Freeing unused kernel memory: 1360k freed Freeing unused kernel memory: 1960k freed After: $ dmesg | grep 'Freeing unused kernel memory' Freeing unused kernel memory: 1236k freed Freeing unused kernel memory: 1388k freed Freeing unused kernel memory: 1960k freed Link: http://lkml.kernel.org/r/5125877D.5000201@huawei.com Signed-off-by: Li Zefan <lizefan@huawei.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
