Subject: [PATCH 05/25] vinyl: fold vy_delete_impl
Date: Fri, 27 Jul 2018 14:29:45 +0300	[thread overview]
Message-ID: <b368902d5ab1b29e5c436cd7649d95f789a0475c.1532689066.git.vdavydov.dev@gmail.com> (raw)

In-Reply-To: <cover.1532689065.git.vdavydov.dev@gmail.com>

vy_delete_impl helper is only used once in vy_delete and it is rather
small so inlining it definitely won't hurt. On the contrary, it will
consolidate DELETE logic in one place, making the code easier to follow.
