[Tarantool-patches] [PATCH v3 2/2] memtx: allow quota overuse for truncation and deletion

[Ilya Kosarev]

From memtx_tuple_new() we call smalloc(). In case it is calling
mempool_alloc(), we are passing the pool from memtx->alloc, chosen
depending on it's size. Later this tuple may be deleted. Then smfree()
is called, which uses mempool_find() to acquire the pool we want to
free.
In case we are using some other specific pool, current mempool_find()
won't be able to find it. This means we need to process this case
explicitly and it seems to add noticeable unjustified complexity to the
code.
