Subject: [RFC][PATCH 1/4] tracing: Rename check_ignore_pid() to ignore_this_task()
Date: Tue, 19 Apr 2016 10:34:22 -0400 [thread overview]
Message-ID: <20160419143725.104178074@goodmis.org> (raw)
In-Reply-To: 20160419143421.829909157@goodmis.org
[-- Attachment #1: 0001-tracing-Rename-check_ignore_pid-to-ignore_this_task.patch --]
[-- Type: text/plain, Size: 2578 bytes --]
From: Steven Rostedt <rostedt@goodmis.org>
The name "check_ignore_pid" is confusing in trying to figure out if the pid
should be ignored or not. Rename it to "ignore_this_task" which is pretty
straight forward, as a task (not a pid) is passed in, and should if true
should be ignored.
