[PATCH v2 0/3] migration: Make save/load_snapshot() return boolean

[Philippe Mathieu-Daudé]

Since v1:
- Initialize variables in first patch (Max)
- Added Pavel's A-b tag

I had a pair of patches making save_snapshot/load_snapshot()
return a boolean (like Markus recent qdev/QOM cleanup), then
realized Daniel already has series changing migration/, so I
rebased my patches in the first part of his v6 series:
"migration: bring improved savevm/loadvm/delvm to QMP"
https://lists.gnu.org/archive/html/qemu-devel/2020-10/msg02158.html

I included patch #1/#3 from Daniel, #2 is my first patch,
and my second patch is squashed with Daniel's #3.

Daniel if you find these patches worthwhile, please consider them
while merging your series (or respining).

Regards,

Phil.

Daniel P. Berrangé (2):
  block: push error reporting into bdrv_all_*_snapshot functions
  migration: stop returning errno from load_snapshot()
