[Qemu-devel] [PATCH for-1.4 0/2] block-migration: fix pending() and iterate() return values

[Stefan Hajnoczi]

This series finally ensures that we never complete block migration before the
entire disk image has been transferred.

Juan explained to me on IRC yesterday what the .save_live_pending() and
.save_live_iterate() are supposed to return.  I had misunderstood them when
reading outdated code in savevm.c and 2c5a7f20112615ce13a3434ab90bee1ed8d44ebd
does not prevent block migration from completing too early.

See the patch descriptions for an explanation of what the .save_live_pending()
and .save_live_iterate() return values mean.
