patch for splice system call.

patch for splice system call.

[Deven Balani]

Hi All!

I am routing data from a tuner to harddisk.
I came to know splice() is something related to do real-time IO.
I believe direct IO doesn't address this scenario.

Can any one refer me the source to the patch of splice() system call.

Regards,
Deven
