[Juan Quintela]

Hi Anthony

This are the migration patches on the list at the moment, could you apply?

* cleanup patches from Isaku
* change is_zero_page() prototype
* cleanups from Lei Li
* cleanup from Christoffer Dall
* new VMSTATE macro from Alexey

They are quite easy, passed virt-test without trouble.


Thanks, Juan.

[Qemu-devel] [PATCH 1/9] savevm: add comments for qemu_file_get_error()

[Juan Quintela]

From: Lei Li <lilei@linux.vnet.ibm.com>

Add comments for qemu_file_get_error(), as its return value
is not very clear.

[Juan Quintela]

From: Lei Li <lilei@linux.vnet.ibm.com>

It should set negative error value rather than 0 in QEMUFile
if there has been an error.

[Juan Quintela]

From: Lei Li <lilei@linux.vnet.ibm.com>

qemu_file_rate_limit() never return negative value since the refactor
by Commit 1964a39, this patch gets rid of the negative check for it,
adjust bytes_transferred and return value correspondingly in
ram_save_iterate().

[Qemu-devel] [PATCH 4/9] rdma: clean up of qemu_rdma_cleanup()

[Juan Quintela]

From: Isaku Yamahata <yamahata@private.email.ne.jp>

- It can't be determined by RDMAContext::cm_id != NULL if the connection
  is established or not.
- RDMAContext::cm_id is leaked and not destroyed because it is set to NULL
  too early.
- RDMAContext::qp is created by rdma_create_qp() so that it should be destroyed
  by rdma_destroy_qp(). not ibv_destroy_qp()

this is buffer_is_zero(p, size); maybe this function should be used.
