Subject: Re: [[PATCH v1] 15/37] [CIFS] SMBD: Post a SMBD data transfer
 message with data payload

You can always get the struct page for kernel allocations using
virt_to_page (or vmalloc_to_page, but this code would not handle the
vmalloc case either), so I don't think you need this helper and can
always use the one added in the previous patch.
