Subject: [PATCH] sched/preempt: Rename PREEMPT_CHECK_OFFSET to
PREEMPT_DISABLE_OFFSET
commit 90b62b5129d5cb50f62f40e684de7a1961e57197 upstream.
"CHECK" suggests it's only used as a comparison mask. But now it's used
further as a config-conditional preempt disabler offset. Lets
disambiguate this name.
