Be prepared to be flamed for that on lkml, using /proc for stuff like that (i.e. driver specifix settings) is depricated these days. It should go to sysfs instead. I can come up with a patch for that, might take some days though as I'm busy with some non-xen stuff at the moment. cheers, Gerd btw: can whoever runs the changelog list (rik?) please add the repository (2.0, unstable, ...) to to subject line please? And while you are at it: -p1 for the diffstat would be cool as well, especially for one-file commits, there are -- for example -- plenty of page.h files in the tree. Thanks. -- #define printk(args...) fprintf(stderr, ## args)
