From 0d206a3af4329bd833cfa5fe1cc7fe146e49c131 Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Wed, 9 Nov 2005 10:35:30 -0800 Subject: [PATCH] [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 Acked-by: Jay Vosburgh Signed-off-by: John W.
