From: David Woodhouse <d...@amazon.co.uk>The refcounts actually correspond to 'active_ref' structures stored in a GHashTable per "user" on the backend side (mostly, per XenDevice). If we zero map_track[] on reset, then when the backend drivers get torn down and release their mapping we hit the assert(s->map_track[ref] != 0) in gnt_unref(). So leave them in place. Each backend driver will disconnect and reconnect as the guest comes back up again and reconnects, and it all works out OK in the end as the old refs get dropped.
