From 25ef756385ce01834504977c22bcce8d8f000e5b Mon Sep 17 00:00:00 2001 From: Alexander Schmidt Date: Wed, 27 Jan 2010 17:01:56 +0000 Subject: [PATCH] IB/ehca: Do not turn off irqs in tasklet context The irq_spinlock is only taken in tasklet context, so it is safe not to disable hardware interrupts.
