Subject: Re: [RESEND PATCH] aio: Add support for the POLLFREE

Hi, Ramji,

Thanks for the explanation of the use after free.  I went ahead and
ran the patch through the libaio test suite and it passed.

> -#define POLLFREE	(__force __poll_t)0x4000	/* currently only for epoll */
> +#define POLLFREE	((__force __poll_t)0x4000)

You added parenthesis, here, and I'm not sure if that's a necessary part
of this patch.

Other than that:
