The linux-2.6.23-utrace.patch there is an old one I didn't bother to delete since it might still apply. But if you are going to use a stable kernel, then you should be using the appropriate backport patch series, i.e. roland/utrace/2.6.23/. The 2.6.23 backport is against 2.6.23, not 2.6.23.y, so a more recent .y can have (and has just) changed the context so the patch doesn't apply. I basically just maintain the backport for the Fedora kernels to use, so generally I'll try to keep it rebased to the .y that Fedora is using. But sometimes the Fedora kernel maintainers will just fix up a patch conflict without poking me, so I might not notice that the "official" utrace backport fell behind. I've just now updated the backport series to apply to 2.6.23.9. If you are doing development with utrace, and especially on utrace itself, then the preferred thing is to work with the bleeding edge kernel from Linus's tree du jour (at the moment I don't think it has changed in ways that mattered since before v2.6.24-rc5). That is what the 2.6-current/ patch series applies to. I recommend applying the series using quilt (or using my GIT branches), though applying just the big linux-2.6-utrace.patch should work too. Thanks, Roland
