Subject: [PATCH v3 02/21] parallels: Move inactivation code to a separate function
Date: Fri, 27 Oct 2023 09:46:17 +0200	[thread overview]
Message-ID: <20231027074636.430139-3-alexander.ivanov@virtuozzo.com> (raw)
In-Reply-To: <20231027074636.430139-1-alexander.ivanov@virtuozzo.com>

We are going to add parallels image extensions storage and need a separate
function for inactivation code.
