drbd_adm_down() does adm_detach(), which can fail with various error codes, or be interrupted by a signal. The interrupted by signal case was not properly handled, leading to block drbd0: ASSERT( mdev->state.disk == D_DISKLESS && mdev->state.conn == C_STANDALONE ) in drbd/drbd_worker.c and further to destroying objects while still in use, and resulting crashes. Detect the interruption, and take the error path out. Signed-off-by: NPhilipp Reisner <philipp.reisner@linbit.com> Signed-off-by: NLars Ellenberg <lars.ellenberg@linbit.com>
