erp. posix_timers has its own irq-safe lock, so we're doing extra, unneeded locking in that code path.
I think providing locking inside idr.c was always a mistake - generally we rely on caller-provided locking for such things. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
