#1366818 — linux-next: manual merge of the rcu tree with Linus' tree

Hi Paul,

Today's linux-next merge of the rcu tree got a conflict in:

  kernel/rcu/tree.c

between commit:

  abedf8e2419f ("rcu: Use simple wait queues where possible in rcutree")

from Linus' tree and commit:

  08cace5914ea ("DIAGS: Crude exploratory hack")

from the rcu tree.

I fixed it up (I used the rcu tree version) and can carry the fix as
necessary. This is now fixed as far as linux-next is concerned, but any
non trivial conflicts should be mentioned to your upstream maintainer
when your tree is submitted for merging.  You may also want to consider
cooperating with the maintainer of the conflicting tree to minimise any
particularly complex conflicts.

I really don't think that that rcu tree patch should be in linux-next,
right?

Cheers,
Stephen Rothwell

Right you are!  I will rework to get the diagnostics out of your way.
-Might- have helped find one of the bugs, but don't look now...

							Thanx, Paul
