Subject: [PATCH 06/11] mpt2sas: Convert to host_lock less w/ interrupts disabled externally
Date: Thu, 11 Nov 2010 16:14:13 -0800	[thread overview]
Message-ID: <1289520853-16550-1-git-send-email-nab@linux-iscsi.org> (raw)

From: Nicholas Bellinger <nab@linux-iscsi.org>

This patch converts the mpt2sas driver to run in host_lock less mode
with the new IRQ_DISABLE_SCSI_QCMD() that disables interrupts while
calling ->queuecommand() dispatch
