14 * Note that, due to trying to use names similar to the protocol specifications,
15 * there are many mixed case field names in the structures below. Although
16 * this does not match typical Linux kernel style, it is necessary to be
17 * able to match against the protocol specfication.

19 * SMB2 commands
20 * Some commands have minimal (wct=0,bcc=0), or uninteresting, responses
21 * (ie no useful data other than the SMB error code itself) and are marked such.
22 * Knowing this helps avoid response buffer allocations and copy in some cases.
