[RFC] gelf - user space probe debugger

[Jiri Olsa]

hi,

I started a debugger project.  It's based on the user space backport
of optimized kprobes (djprobes) and RSP stub implementation.

The debugger is implemented as a preloaded shared library,
which handles all the debugger work, hence no kernel ptrace
is needed.

It just reached the state where it can handle simple gdb session
of setting/reaching a breakpoint and continue the execution.

Details can be found on http://people.redhat.com/jolsa/gelf/

I'd like to ask for opinions if there'd be users for such thing,
and if it's worth to continue on this..

thanks for any ideas,
jirka
