Junjie Mao 17771c0ac2 HV: io: refine state transitions of VHM requests ... Instead of using two members for maintaining the state of a VHM request, this patch replaces the transitions with a single state. Basically the lifecycle of a VHM request shall be: FREE -> PENDING -> PROCESSING -> COMPLETE -> FREE -> ... The structure header of vhm_request has more details of the transitions access limitations under different states. Also drop the set but unused member vcpu.ioreq_pending. For backward-compatibility, the obsolete 'valid' member is still kept and maintained before SOS and DM adapts to the new state transitions. v2 -> v3: * Use complete_ioreq to mark an I/O request finished in dm_emulate_(pio|mmio)_post.
