6 * Note that, due to trying to use names similar to the protocol specifications,
7 * there are many mixed case field names in the structures below. Although
8 * this does not match typical Linux kernel style, it is necessary to be
9 * able to match against the protocol specfication.
10 *
11 * SMB2 commands
12 * Some commands have minimal (wct=0,bcc=0), or uninteresting, responses
13 * (ie no useful data other than the SMB error code itself) and are marked such.
14 * Knowing this helps avoid response buffer allocations and copy in some cases.
