Subject: [Tarantool-patches] [PATCH luajit v2 4/7] core: introduce new mem_L field
Date: Fri, 25 Dec 2020 18:26:06 +0300	[thread overview]
Message-ID: <47fe3e90153279081caedd4799a0e0dffdfac7be.1608907726.git.skaplun@tarantool.org> (raw)
In-Reply-To: <cover.1608907726.git.skaplun@tarantool.org>

To determine currently allocating coroutine (that may not be equal to
currently executed one) a new field called mem_L is added to
global_State structure. This field is set on each allocation event and
stores the coroutine address that is used for allocation.
