Hmm, to me it seems as if some grant isn't being unmapped.
Looking at gnttab_unmap_refs_async() I wonder how this is supposed to
work:
I don't see how a grant would ever be unmapped in case of
page_count(item->pages[pc]) > 1 in __gnttab_unmap_refs_async(). All it
does is deferring the call to the unmap operation again and again. Or
am I missing something here?
