NFSv4.1: pnfs: add LAYOUTGET and GETDEVICEINFO infrastructure 2010-10-24T22:07:10+00:00 Andy Adamson andros@netapp.com 2010-10-20T04:18:03+00:00 b1f69b754ee312ec75f2c7ead0e6851cd9598cc2 Add the ability to actually send LAYOUTGET and GETDEVICEINFO. This also adds in the machinery to handle layout state and the deviceid cache. Note that GETDEVICEINFO is not called directly by the generic layer. Instead it is called by the drivers while parsing the LAYOUTGET opaque data in response to an unknown device id embedded therein. RFC 5661 only encodes device ids within the driver-specific opaque data.
