Well, since I just moved the marker iterators down in my patchset, I can move down the module list fix altogether and keep it for later. It will make the patchset as unintrusive as possible. > I'd say we probably don't want the blktrace conversion that late in the > game, though - but we can queue that once together with the optimizations > from Mathieu's earlier patches in -mm. > I provided blktrace as a first user of the markers, but I agree that it may be a little late for merging. I can keep it for later too.
