Re: [PATCH 2/6] ibmvscsi: Add and use enums for valid CRQ header values

Yeah, I can see how that is confusing. Since, all three possible valid
crq message types have the first bit set I think this was originally a
cute hack to grab anything that was likely valid. Then in
ibmvscsi_handle_crq() we explicitly match the full header value in a
switch statement logging anything that turned out actually invalid.


If 'valid' will only have one of these four enums defined, would
this be better written as:

if (crq->valid != VIOSRP_CRQ_FREE)

This definitely would make the logic easier to read and follow. Also,
this would make sure any crq with an invalid header that doesn't have
its first bit set will also be logged by the ibmvscsi_handle_crq()
switch statement default block and not silently ignored.

Sounds good, Tyrel. Does this mean I should expect a v2 of this patch
series?
