Subject: [PATCH] libtracefs: Define gettid() when not defined
Date: Wed, 25 Aug 2021 19:45:43 -0400 [thread overview]
Message-ID: <20210825194543.34de6c3f@rorschach.local.home> (raw)
From: Steven Rostedt <rostedt@rorschach.local.home>
tracefs-hist.c uses the gettid() system call, but older glibcs do not
define it. Define the system call when it is not already defined.
Signed-off-by: Steven Rostedt <rostedt@rorschach.local.home>
