Subject: [PATCH] Corrections in Documentation/block/ioprio.txt

Hi Jens,

The newer glibc does not allow system calls to be made via _syscallN()
wrapper. They have to be made through syscall(). The ionice code used
the older interface. Correcting it to use syscall.

I would like to change the world but they don't give me the source code!
