Subject: [PATCH v3 03/21] parallels: Make mark_used() a global function
Date: Fri, 27 Oct 2023 09:46:18 +0200	[thread overview]
Message-ID: <20231027074636.430139-4-alexander.ivanov@virtuozzo.com> (raw)
In-Reply-To: <20231027074636.430139-1-alexander.ivanov@virtuozzo.com>

We will need this function and a function for marking unused clusters (will
be added in the next patch) in parallels-ext.c too. Let it be a global
function parallels_mark_used().
