Subject: [PATCH v2 10/23] KVM: selftests: Stop using __virt_pg_map() directly in tests
Date: Tue, 21 Oct 2025 07:47:23 +0000	[thread overview]
Message-ID: <20251021074736.1324328-11-yosry.ahmed@linux.dev> (raw)
In-Reply-To: <20251021074736.1324328-1-yosry.ahmed@linux.dev>

Replace __virt_pg_map() calls in tests by high-level equivalent
functions, removing some loops in the process.

No functional change intended.
