Takashi-san's description was not very clear, but it sounds like it's a patching mechanism for userspace applications - not for kernel space. So kprobes would not be a good fit. If I'm right, I'm not sure why some of the bits of it were done separately instead of via the existing ptrace mechanism. And GDB would appreciate a mechanism for mmap/munmap/mprotect in a debugged process, also. -- Daniel Jacobowitz CodeSourcery, LLC - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
