Hi
I want to disable persistent grant in xen. I tried to use xenbus to
disable it. What I did is modifying this line in
drivers/block/xenblkback/xenbus.c:
791 err = xenbus_printf(xbt, dev->nodename, "feature-persistent", "%u",
1);
and put this
791 err = xenbus_printf(xbt, dev->nodename, "feature-persistent", "%u",
0);
but the problem is my domain crash.
I think it is not the only thing to do in order to disable persistent
grant.
Please can you help me.
Thank you
HANNAS
