Some parts of the code assumed that get_ldev_if_state(device, D_ATTACHING) is sufficient to access the ldev member of the device object. That was wrong. ldev may not be there or might be freed at any time if the device has a disk state of D_ATTACHING. bm_rw() Documented that drbd_bm_read() is only called from drbd_adm_attach. drbd_bm_write() is only called when a reference is held, and it is documented that a caller has to hold a reference before calling drbd_bm_write() drbd_bm_write_page() Use get_ldev() instead of get_ldev_if_state(device, D_ATTACHING) drbd_bmio_set_n_write() No longer use get_ldev_if_state(device, D_ATTACHING). All callers hold a reference to ldev now. drbd_bmio_clear_n_write() All callers where holding a reference of ldev anyways. Remove the misleading get_ldev_if_state(device, D_ATTACHING) drbd_reconsider_max_bio_size() Removed the get_ldev_if_state(device, D_ATTACHING). All callers now pass a struct drbd_backing_dev* when they have a proper reference, or a NULL pointer. Before this fix, the receiver could trigger a NULL pointer deref when in drbd_reconsider_max_bio_size() drbd_bump_write_ordering() Used get_ldev_if_state(device, D_ATTACHING) with the wrong assumption. Remove it, and allow the caller to pass in a struct drbd_backing_dev* when the caller knows that accessing this bdev is safe.
