[Qemu-devel] [PATCH V2 0/7] Make QED with live migration safe

[Benoît Canet]

This is the second version of a patchset aiming at making the combined
usage of QED and live migration safe.

Since v1:

-The block layer is not aware anymore of the migration state. (stefanha)
-No bdrv_invalidate_cache renaming since the semantic do not change. (stefanha)
-The qed bdrv_invalidate_cache function does a reopening of the image to flush
 metadata and to do the image integrity check. (stefanha)

note:

In "qed: honor BDRV_O_INCOMING for incoming live migration" I choose to
honor bs->open_flags and not s->flags in order to keep the
bdrv_qed_invalidate_cache function intact of any migration related operation.
This way bdrv_qed_invalidate_cache semantic is not changed.

Benoît Canet (7):
  block: Add new BDRV_O_INCOMING flag to notice incoming live migration
  block: add a function to clear incoming live migration flags
  blockdev: open images with BDRV_O_INCOMING on incoming live migration
  qed: add bdrv_invalidate_cache to be called after incoming live
    migration
  migration: clear BDRV_O_INCOMING flags on end of incoming live
    migration
  qed: honor BDRV_O_INCOMING for incoming live migration
  qed: remove incoming live migration blocker
