[PATCH] aio: Fix type of iterator variable in do_io_submit()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



do_io_submit() iterated over the userspace iocb structure pointers using
a variable i of type 'int'.  This was wrong since 'nr', the number of
iocb structure pointers, could potentially be up to LONG_MAX /
sizeof(struct iocb *).  Fix it (and also remove the unnecessary
initialization to 0).
