Re: INFO: possible recursive locking detected: get_partial_node()on 3.2-rc1

Looks like a false positive.

put_cpu_partial() can be called with a parameter to indicate if draining
of the per cpu partial list should be allowed ("drain"). Draining requires
taking the list lock. "drain" is set to 0 when called from
get_partial_node() (where we are already holding the list lock) so no
deadlock should be possible.
