linux-next: manual merge of the sysctl tree with the rcu tree

linux-next: manual merge of the sysctl tree with the rcu tree

Hi all,

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

  kernel/rcu/rcu.h

between commit:

  95d4e9e339d1 ("rcu: Provide a get_completed_synchronize_rcu() function")

from the rcu tree and commit:

  d9ab0e63fa7f ("sched: Move rt_period/runtime sysctls to rt.c")

from the sysctl tree.

I fixed it up (see below) 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.

Cheers,

Thank you, Stephen!  I have this one marked down.
