[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v6 06/12] x86/hvm/ioreq: rename .*pfn and .*gmfn to .*gfn
Since ioreq servers are only relevant to HVM guests and all the names in
question unequivocally refer to guest frame numbers, name them all .*gfn
to avoid any confusion.
This patch is purely cosmetic. No semantic or functional change.
