30 * Note that, due to trying to use names similar to the protocol specifications,

32 * this does not match typical Linux kernel style, it is necessary to be
33 * be able to match against the protocol specfication.

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