Subject: kthread: unexport __kthread_should_park()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=be33db21427c33a4217bd6b805944d2cf84faf25;p=linux.git

kthread: unexport __kthread_should_park()

There are no in-kernel users of __kthread_should_park() so mark it as
static and do not export it.
