Ok, will take a look. > Things that would be interesting to explain/document: > * what is special about vmxnet3 that makes it the only pci device > that needs to use this rather than having a vmstate struct? Will take a look. vmxnet3 used to be a mess (in relation to migration). > * why does s390-skeys call the register function with a NULL > pointer but the unregister pointer with a device pointer? No clue, will left that > (Could we replace the uses of these which pass a dev pointer > with vmstate structs and then drop the dev parameter?) Not sure, have to take a look. Thanks, Juan.
