Patch #20/20 in the set includes an ftrace-flavoured debugfs frontend.
Previous versions of the patchset included perf front-ends too, which
are probably to be seen again.

The code is not currently useful to gdb. Perhaps ptrace or an
improved userspace ABI can get access to it in the form of a
breakpoint-management interface, though this inode+offset
style of uprobe addressing would require adaptation to the
process-virtual-address style used by debugging APIs.
