[Qemu-devel] [PATCH V3 0/7] Make QED with live migration safe |

This is the third version of a patchset aiming at making the combined
usage of QED and live migration safe.
v3:
-qed: Drop the flags qed structure member and use bs->open_flags to reopen
(stefana)
-qed: When opening honor flags parameter instead of bs->open_flags
v2:
-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)
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
