Subject: [PATCHSET 0/2] Get rid of import_single_range()

Hi,

While looking at this today, I noticed that the 'iov' argument to this
function is totally dead code. Patch 1 gets rid of it, and with this
function and import_ubuf() now being identical, converts the callers
to just use import_ubuf().

No functional changes here, just a cleanup removing some dead code.
