However, I had to fix up the title of your patch. Please don't screw it up like this, and just use: git format-patch --subject-prefix="PATCH v2" and no other weird thing. Your patch title should have brackets inside brackets, i.e the title should look like: [PATCH v2 1/1] lttng-libust... or even better, for a single patch: [PATCH v2] lttng-libust...
