[PATCH v2 0/2] PM: hibernate: Drain trailing zero pages on userspace restore

[Alberto Garcia <berto@igalia.com>]

Hi,

Here's v2 of the patch.

Changes from v1:

- The extra snapshot_write_next() call happens now at the beginning of
  snapshot_write_finalize(), but only when handle->cur is in the data
  page region.

- We return -ENODATA if snapshot_write_next() returns > 0 (indicating
  that the kernel was expecting another page).

- A second patch changes the userspace restore code to return -ENODATA
  when snapshot_image_loaded() fails.

Regards,

Berto
