stable inclusion from stable-5.10.9 commit 0eb56457d239f5ee555ad9dc0c086a0abd933f1b bugzilla: 47457 -------------------------------- commit 0378c625 upstream. There wasn't ever a real need to log an error in the kernel log for ioctls issued with insufficient permissions. Simply return an error and if an admin/user is sufficiently motivated they can enable DM's dynamic debugging to see an explanation for why the ioctls were disallowed. Reported-by: NNir Soffer <nsoffer@redhat.com> Fixes: e980f623 ("dm: don't allow ioctls to targets that don't map to whole devices") Signed-off-by: NMike Snitzer <snitzer@redhat.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: NChen Jun <chenjun102@huawei.com> Acked-by: NXie XiuQi <xiexiuqi@huawei.com>
