Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring: check if we need to reschedule during overflow flush
In terms of normal application usage, this list will always be empty.
And if an application does overflow a bit, it'll have a few entries.
However, nothing obviously prevents syzbot from running a test case
that generates a ton of overflow entries, and then flushing them can
take quite a while.
Check for needing to reschedule while flushing, and drop our locks and
do so if necessary. There's no state to maintain here as overflows
always prune from head-of-list, hence it's fine to drop and reacquire
the locks at the end of the loop.

Sin embargo, obviamente nada impide que syzbot ejecute un caso de prueba que genere un mont\u00f3n de entradas de desbordamiento, y luego vaciarlas puede llevar bastante tiempo. Verifique la necesidad de reprogramar durante el vaciado y elimine nuestros bloqueos y h\u00e1galo si es necesario. No hay ning\u00fan estado que mantener aqu\u00ed, ya que los desbordamientos siempre se podan desde el principio de la lista, por lo tanto, est\u00e1 bien eliminar y volver a adquirir los bloqueos al final del bucle."
