| H A D | preempt.h | diff 847d357635ce4c63b8901ab81333586a0f115fa5 Wed Dec 14 17:08:02 CST 2016 Matthew Wilcox <willy@infradead.org> radix tree test suite: track preempt_count
Rather than simply NOP out preempt_enable() and preempt_disable(), keep
track of preempt_count and display it regularly in case either the test
suite or the code under test is forgetting to balance the enables &
disables. Only found a test-case that was forgetting to re-enable
preemption, but it's a possibility worth checking.
