Bad comment. It's unclear what this patch actually does to fix the
issue. Looks like you didn't bother to rewrite it in v2.

I fixed it and pushed the patch to 2.1

Invalid link. BTW, "Issue:" and "Branch:" are usless.

Also, changelog since v2 is missing. And it would be prudent to put
a link here to v1, like this:

Changes in v2:
 - Use malloc() in memtx instead of region_alloc().
 - Truncate region in engine callbacks rather than in box_snapshot().

v1: https://www.freelists.org/post/tarantool-patches/PATCH-v1-11-box-restore-region-after-boxsnapshot
