Subject: linux-next: manual merge of the tip tree with the mm-unstable tree
Hi all,
Today's linux-next merge of the tip tree got a conflict in:
mm/vmstat.c
between commit:
954386324a11 ("mm/vmstat: utilize designated initializers for the vmstat_text array")
from the mm-unstable tree and commit:
8662a3e5e9c4 ("Revert "sched/numa: add statistics of numa balance task"")
from the tip tree.
I fixed it up (see below - search for NUMA_BALANCING) 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 assume that this will go away when the Revert above goes into Linus'
tree (or returns to the mm-hotfixes tre).

Cheers,
Stephen Rothwell
