30 | * Note that, due to trying to use names similar to the protocol specifications, | |
31 | * there are many mixed case field names in the structures below. Although | |
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. | |
