What do you mean? If you have a DIX-capable HBA (lpfc, qla2xxx, zfcp) then integrity protection is active from the block layer down. The only code that's not currently being exercised are the tag interleaving functions. I was hoping the FS people would use them for back pointers but nobody seemed to bite.

I don't understand why multiqueue would require a lot of work? It's just an extra scatterlist per request. And obviously, if there's anything that needs to be done in this area I'll be happy to do so... -- Martin K.
