Hi Nikanth,

Thanks for this!

I'll reword this as

==
Attempts to set very high priorities
.RB ( IOPRIO_CLASS_RT )
require the
.B CAP_SYS_ADMIN
capability.
Kernel versions up to 2.6.24 also required
B CAP_SYS_ADMIN
to set very low priority
.RB ( IOPRIO_CLASS_IDLE ),
but since Linux 2.6.24 this is no longer required.
==

Okay?

The change will be in man-pages-3.04.

Cheers,

Michael

And I fixed my typo there: "since Linux 2.6.25..."
