Revision 466 contains the mutex-info fix, but that is post -rc2. Why not
switching to SVN head?
Philippe asked to apply the patch against Xenomai 2.1-rc2. Can I safely patch it against the SVN tree ? After that, what will 'svn up' do to the patched tree ?
Remember I'm quite new to Linux. Actually, I spent half an hour finding out how that patch stuff (especially the -p option) works.
