Subject: [PATCH] libtracefs: Set the long size of the tep handle in tracefs_local_events_system()
Date: Fri, 22 Jul 2022 14:28:03 -0400	[thread overview]
Message-ID: <20220722142803.24919c8a@gandalf.local.home> (raw)

From: "Steven Rostedt (Google)" <rostedt@goodmis.org>

While writing a workshop on using libtracefs, I found that it was
embarrassing that tracefs_local_events() does not set it, and failed some
parsing that relies on it. (tracefs_local_events() simply calls
tracefs_local_events_system() where the fix needs to be added).

Set the long size of the event using:

  tep_set_long_size(tep, tep_get_header_page_size(tep))

(oh, and that tep_get_header_page_size() is HORRIBLY misnamed!!!)
