The object\nis then freed without being removed from its owner's idr, and the owner\nsession later dereferences the stale pointer during file-table teardown.\n\nRemove the volatile id from the owner's idr while ksmbd_close_fd() still\nholds that table's lock, and clear volatile_id before dropping\nthe idr-owned reference. A later foreign final put then only performs\nphysical destruction and cannot remove the object from the wrong table.",
