From c5fa46e175ccd02803031ea071060cdb01521736 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Tue, 20 Jun 2006 05:08:44 -0400 Subject: [libata] sata_nv: s/spin_lock_irqsave/spin_lock/ in irq handler We don't need to use the heavier spin lock in the irq handler. It's quite possible we can do this in nv_generic_interrupt() as well, but I didn't take the time to pursue that train of thought.
