If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 5b5a06ed01c5416a4df2c6cef8a547c0c682d5c9 Author: Jeff Layton <jlayton@xxxxxxxxxx> Date: Tue Mar 19 12:32:04 2024 -0400 vboxsf: explicitly deny setlease attempts [ 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.
