Hi Stephen, At LSFMM we're talking about the need to do more integrated testing with the various fs trees, the fs infrastructure and the vfs. We'd like to avoid that testing be blocked by a bad patch in, say, a graphics driver. A solution we're kicking around would be for linux-next to include a 'fs-next' branch which contains the trees which have opted into this new branch. Would this be tremendously disruptive to your workflow or would this be an easy addition?
