From 7a5fb579f7b435cffa7e323f4be5a4d28a24e753 Mon Sep 17 00:00:00 2001 From: Sven-Thorsten Dietrich Date: Fri, 3 Jul 2009 08:30:35 -0500 Subject: [PATCH 082/365] infiniband: Mellanox IB driver patch use _nort() primitives Fixes in_atomic stack-dump, when Mellanox module is loaded into the RT Kernel. Michael S. Tsirkin sayeth: "Basically, if you just make spin_lock_irqsave (and spin_lock_irq) not disable interrupts for non-raw spinlocks, I think all of infiniband will be fine without changes."
