Subject: [PATCH 10/22] virt/kvm: Use vma_lookup() instead of find_vma_intersection()
Date: Mon, 10 May 2021 16:58:53 +0000	[thread overview]
Message-ID: <20210510165839.2692974-11-Liam.Howlett@Oracle.com> (raw)
In-Reply-To: <20210510165839.2692974-1-Liam.Howlett@Oracle.com>

vma_lookup() finds the vma of a specific address with a cleaner
interface and is more readable.
