And it turns out that today I am feeling the same way again as I said so
here:
	https://lore.kernel.org/lkml/20130711214830.611455274@linuxfoundation.org/

Looking at the patches in this -rc1 merge window that were marked for
stable, and some of the dates of them (really old for some subsystems),
it makes me "wonder" why they were postponed so for -rc1, and didn't go
into the -final release.

I know I have done this for "small" patches, or stuff that comes in late
in the -rc cycle that just really does not matter much.  Or for things
that I want to see "bake" in linux-next more.  But even with that, I
don't think that's what is happening here, I think maintainers are just
waiting until -rc1 as it's "easier".   I really have no other
explaination.

Now I can't reject the patches as they are good fixes, and they are now
in Linus's tree.  But the "delay" is worrying to me.  I don't know what
to do about it...

Look at what comes out in this next round of stable releases, and tell
me that all of those really deserved to wait for -rc1.
