We are working on in-kernel gdbstub which was one of the features that
you had asked for. gdbstub does pass unit tests; but we are looking at
some way to hack the GDB testsuite to run its regression tests. Once we
are able to run the GDB testsuite and utrace is part of some upstream
tree, we plan to post these patches to LKML for comments. gdbstub uses
utrace and uprobes underneath. Uprobes was rewritten to remove issues
that LKML developers had opposed. Uprobes also has its own ftrace plugin
to use uprobes.

Currently in-kernel gdbstub is hosted by Frank Ch. Eigler over here:
git://web.elastic.org/~fche/utrace-ext.git
branch name utrace-gdbstub-uprobes
