I've tried to quilt push -a both LTTng 0.89 and LTTng 0.92 taken from the website and they both apply correctly on 2.6.29-rc3. When I quilt pop -a, neither of those 3 files (include/linux/ltt-core.h, ltt/ltt-core.c, ltt/ltt-relay.c) are stucked in my tree. I've used files from : http://www.lttng.org/files/lttng/patch-2.6.29-rc3-lttng-0.92.tar.bz2 Which tarballs are you using exactly ? I guess you need to apply them to your existing tree, so pointing you to git.kernel.org lttng tree won't help much here.
