Doing this from kernelspace is wrong. It should be done from userspace, best using a systemcall. Of couse the handlers can't work as-is you'd need to redo that to work similarlt to ptrace - which will hopefully allow some code reuse aswell.
And please - independent of the best api in this case - please don't ever submit large amounts of code again that don't have any in-tree user. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
