[tarantool-patches] Re: [PATCH 2/3] txn: merge struct sql_txn into struct txn

[Vladislav Shpilevoy <v.shpilevoy@tarantool.org>]

Hi! Thanks for the fixes! Mine is in a separate commit
on the branch (after "txn: merge struct sql_txn into struct txn"),
and below. Please, squash if you are ok with that.

Talking of savepoint duplicate names - it is a bug existing in 2.2.1
too. I think, we should backport the fix. Or not. Up to Kirill.
