Subject: [PATCH 06/34] accel/accel-irq: add generic commit_route_changes
Date: Fri, 17 Apr 2026 12:55:50 +0200	[thread overview]
Message-ID: <20260417105618.3621-7-magnuskulke@linux.microsoft.com> (raw)
In-Reply-To: <20260417105618.3621-1-magnuskulke@linux.microsoft.com>

A generic accel_irqchip_commit_route_changes() fn has been introduced for
usage in the MSHV accelerator. The respective kvm_ fn can be removed
since we handle the commit op in a generic way.

Signed-off-by: Magnus Kulke <magnuskulke@linux.microsoft.com>
