Subject: [PATCH AUTOSEL 6.6 10/12] vboxsf: explicitly deny setlease attempts
Date: Mon, 15 Apr 2024 06:03:45 -0400 [thread overview]
Message-ID: <20240415100358.3127162-10-sashal@kernel.org> (raw)
In-Reply-To: <20240415100358.3127162-1-sashal@kernel.org>
From: Jeff Layton <jlayton@kernel.org>
[ Upstream commit 1ece2c43b88660ddbdf8ecb772e9c41ed9cda3dd ]
vboxsf does not break leases on its own, so it can't properly handle the
case where the hypervisor changes the data. Don't allow file leases on
vboxsf.
