From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx> Add follow event and missed events callback helper to make it simpler to follow events using the tracefs_iterate_raw_events() function. Also change tracefs_iterate_raw_events() to use the tracefs_cpu_buffered_read() that will read via splice and is much more efficient than using single reads. Changes since v2: https://lore.kernel.org/all/20221115040417.2453172-1-rostedt@xxxxxxxxxxx/ - Fixed up the documentation (again!)
