Dear Keir-san,
Can I ask one question for my correct understanding?

You showed me two options in previous email; i.) all the shared-memory
structures defined in vscsiif.h compile identically for 32-bit and
64-bit mode, ii.) to detect the frontend's 'bitness' in scsiback and
optionally do 32-to-64 or 64-to-32 conversion.
I consider that current VBD implementation takes option ii.), however
you recommended me to take option i.) for pvSCSI driver.
Is my understanding right?
Best regards,
