Sin embargo, mantener 'reconfig_mutex' aqu\u00ed sigue siendo problem\u00e1tico porque esto causar\u00e1 un punto muerto, por ejemplo, confirme 130443d60b1b (\"md: refactor idle/frozen_sync_thread() to fix deadlock\"). Solucione este problema usando stop_sync_thread() para cancelar el registro de sync_thread, como lo hizo md/raid."
