2020-09-18tracing: toplevel d_entry already initializedWei Yang1-7/+2
Currently we have following call flow: tracer_init_tracefs() tracing_init_dentry() event_trace_init() tracing_init_dentry() This shows tracing_init_dentry() is called twice in this flow and this is not necessary. Let's remove the second one when it is for sure be properly initialized.

2020-09-18tools/bootconfig: Add --init option for bconf2ftrace.shMasami Hiramatsu2-1/+120
Since the ftrace current setting may conflict with the new setting from bootconfig, add the --init option to initialize ftrace before setting for bconf2ftrace.sh. E.g. $ bconf2ftrace.sh --init boottrace.bconf This initialization method copied from selftests/ftrace.
