locking/lockdep: increase size of counters for lockdep statistics
When system has been running for a long time, signed integer counters are not enough for some lockdep statistics. Using unsigned long counters can satisfy the requirement. Besides, most of lockdep statistics are unsigned. It is better to use unsigned int instead of int. Remove unused variables. - max_recursion_depth - nr_cyclic_check_recursions - nr_find_usage_forwards_recursions - nr_find_usage_backwards_recursions Signed-off-by: Kobe Wu <kobe-cp.wu@mediatek.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: <linux-mediatek@lists.infradead.org> Cc: <wsd_upstream@mediatek.com> Cc: Eason Lin <eason-yh.lin@mediatek.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Will Deacon <will.deacon@arm.com> Link: https://lkml.kernel.org/r/1561365348-16050-1-git-send-email-kobe-cp.wu@mediatek.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
