And on the whole, everything here is pretty small. The diffstat looks a bit larger for an xfs fix, because that fix has three cleanup refactoring patches that precedes it.

In addition to the above, there's random small fixes all over - shortlog appended for people who want to skim the details as usual.
Go test, and obviously with 4.5 released, I'll start the merge window for 4.6
