For example: That's, um, "interesting", but is of course, nothing we can accept into the main kernel tree, as I'm sure you can understand. Otherwise, you just created a few thousand undocumented system calls whose behavior changes every release which is not something we can accept. But it is a great hack, very nicely done. I'm sure that some people will like it for debugging, although I'm not quite sure you got all of the user/kernel boundry conditions correct, and I know the 32/64bit issues aren't handled, which you might want to clean up sometime in the future. greg k-h _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
