It's done in the last patch where it'll start to pass over "channel" index into
ram_block_from_stream():
static inline RAMBlock *ram_block_from_stream(MigrationIncomingState *mis,
QEMUFile *f, int flags,
int channel)
{
RAMBlock *block = mis->last_recv_block[channel];
...
}
I could have moved it into the new PostcopyTmpPage structure, but it'll be a
bit weird because precopy also uses this to cache the block info, hence I made
it an array.
