38 The KVM x86 tree is organized into multiple topic branches. The purpose of
39 using finer-grained topic branches is to make it easier to keep tabs on an area
45 All topic branches, except for ``next`` and ``fixes``, are rolled into ``next``
57 following rc7 for "normal" releases. If all goes well, the topic branches are
95 dependencies across topic branches, it is the maintainer's job to sort them
166 Note, these don't align with the topics branches (the topic branches care much
340 solution is to derive the names of your development branches based on their
381 patch's SHA1 changes. However, in some scenarios, e.g. if all KVM x86 branches
