Subject: tracing: Rename check_ignore_pid() to ignore_this_task()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9ebc57cfaad21aacbc363eecead579269a46b493;p=openwrt%2Fstaging%2Fblogic.git

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.
