* workqueue: avoid using deprecated functionsLinus Torvalds2012-10-035-18/+18
| | | | | | | | | | | | | The network merge brought in a few users of functions that got deprecated by the workqueue cleanups: the 'system_nrt_wq' is now the same as the regular system_wq, since all workqueues are now non- reentrant. Similarly, remove one use of flush_work_sync() - the regular flush_work() has become synchronous, and the "_sync()" version is thus deprecated as being superfluous.

| * NFC: LLCP raw socket supportThierry Escande2012-09-274-4/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for socket of type SOCK_RAW to LLCP. sk_buff are copied and sent to raw sockets with a 2 bytes extra header: The first byte header contains the nfc adapter index. The second one contains flags: - 0x01 - Direction (0=RX, 1=TX) - 0x02-0x80 - Reserved A raw socket has to be explicitly bound to a nfc adapter. This is achieved by specifying the adapter index to be bound to in the dev_idx field of the sockaddr_nfc_llcp struct passed to bind().
