Any time we do a massive, disruptive change to the code base, it's
going to cause problems to -stable. It means that bug fix patches
won't necessarily auto-apply, and some will require manual fixups
afterwards
Given that this change doesn't really fix any bugs, I'd have to ask
the question --- is it *worth* it? We really need to apply a certain
amount of cost/benefit analysis around this.
If it were really important, the thing we could do is to apply a
single treewide patch at some point after the merge window. I'd
suggest after -rc2, myself, but reasonable people can differ. And
then, if it were *really* important we could run the same script on
the stable kernels.
But for changing "/* fallthrough */" to "fallthrough;"
Does this ***really*** matter? Why are we tying ourselves up in knots
trying to do this all at once?
