Almost only, but not quite. drivers/media/usb/em28xx/em28xx.h: struct rt_mutex i2c_bus_lock; include/linux/i2c.h: struct rt_mutex bus_lock; kernel/rcu/tree.h: struct rt_mutex boost_mtx; -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
