Hi,

I'd like to receive  comments/guide-lines about a hack I made to the
2.6.11 kernel to improve DVD-burning speed (using growisofs.)

The basic idea is the 16-pages pipe between mkisofs and growisofs is
too small for DVD burning (typical 4GB of data.)

In the hack, pipe_new will simply check for, if privileges permitted,
the enviroment variable
PIPE_MAX_ORDER to see if a (much) longer pipe is requested.

This hack enable me to burn DVD at 8X (instead of 3X) on my old
P3-450MHz (with growisofs and mkisofs running at SCHED_FIFO.)
