Bob Liu 11659569f7 xen/blkfront: split per device io_lock ... After patch "xen/blkfront: separate per ring information out of device info", per-ring data is protected by a per-device lock ('io_lock'). This is not a good way and will effect the scalability, so introduce a per-ring lock ('ring_lock'). The old 'io_lock' is renamed to 'dev_lock' which protects the ->grants list and ->persistent_gnts_c which are shared by all rings. Note that in 'blkfront_probe' the 'blkfront_info' is setup via kzalloc so setting ->persistent_gnts_c to zero is not needed.
