[PATCH] bonding: move kmalloc out of spinlock in ALB init
Move memory allocations out of the spinlock during ALB init. This gets rid of a sleeping-inside-spinlock warning and accompanying stack dump. Signed-off-by: Mitch Williams <mitch.a.williams@intel.com> Acked-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
