From f697f74a6b189702474b2fd457e1f9365fa213e3 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 10 Apr 2006 09:43:59 -0700 Subject: [PATCH] IPoIB: Use spin_lock_irq() instead of spin_lock_irqsave() We know ipoib_flush_paths() is called from plain process context with interrupts enabled, since it does wait_for_completion(). So there's no need to use spin_lock_irqsave() -- spin_lock_irq() is fine.
