NFSv4.1: purge deviceid cache on nfs_free_client
Use the pnfs_layoutdriver_type both as a qualifier for the deviceid, distinguishing deviceid from different layout types on the server, and for freeing the layout-driver allocated structure containing the nfs4_deviceid_node. [BUG in _deviceid_purge_client] [layout_driver MUST set free_deviceid_node if using dev-cache] [let ver < 4.1 compile] Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> [removed EXPORT_SYMBOL_GPL(nfs4_deviceid_purge_client)] Signed-off-by: Benny Halevy <bhalevy@panasas.com>
