[Qemu-devel] [PATCH 0/3] backup fixes for 4.1?

[Vladimir Sementsov-Ogievskiy]

Hi all!

Here are two small fixes.

01 is not a degradation at all, so it's OK for 4.2
02 is degradation of 3.0, so it's possibly OK for 4.2 too,
   but it seems to be real bug and fix is very simple, so,
   may be 4.1 is better

Or you may take the whole series to 4.1 if you want.

Vladimir Sementsov-Ogievskiy (3):
  block/backup: deal with zero detection
  block/backup: disable copy_range for compressed backup
  block/backup: refactor write_flags
