Subject: md: raid1/raid10: handle allocation errors during array setup.
X-Git-Tag: v2.6.32-rc6~27^2~11

md: raid1/raid10: handle allocation errors during array setup.

Both raid1 and raid10 create a mempool during startup.
If the 'alloc' function for this mempool fails, unplug_slaves
is called.
If that happens when the pool is being initialised, unplug_slaves
will try to use the 'conf' structure that isn't filled in yet, and
badness will happen.

So ensure that unplug_slaves doesn't get called unless we know
that the conf structure if fully initialised.
