From 9ebc57cfaad21aacbc363eecead579269a46b493 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Tue, 12 Apr 2016 20:39:55 -0400 Subject: [PATCH] tracing: Rename check_ignore_pid() to ignore_this_task() 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.
