From 078efae00ffc76381c3248006e9cf0988163488f Mon Sep 17 00:00:00 2001 From: Anish Bhatt Date: Mon, 15 Sep 2014 17:44:18 -0700 Subject: [SCSI] cxgb4i: avoid holding mutex in interrupt context cxgbi_inet6addr_handler() can be called in interrupt context, so use rcu protected list while finding netdev. This is observed as a scheduling in atomic oops when running over ipv6. Fixes: fc8d0590d914 ("libcxgbi: Add ipv6 api to driver") Fixes: 759a0cc5a3e1 ("cxgb4i: Add ipv6 code to driver, call into libcxgbi ipv6 api") Signed-off-by: Anish Bhatt Signed-off-by: Karen Xie Signed-off-by: Christoph Hellwig Signed-off-by: James Bottomley --- drivers/scsi/cxgbi/cxgb4i/cxgb4i.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/scsi/cxgbi/cxgb4i/cxgb4i.c') diff --git a/drivers/scsi/cxgbi/cxgb4i/cxgb4i.c b/drivers/scsi/cxgbi/cxgb4i/cxgb4i.c index 79788a1..02e69e7 100644 --- a/drivers/scsi/cxgbi/cxgb4i/cxgb4i.c +++ b/drivers/scsi/cxgbi/cxgb4i/cxgb4i.c @@ -1647,7 +1647,7 @@ static int cxgbi_inet6addr_handler(struct notifier_block *this, if (event_dev->priv_flags & IFF_802_1Q_VLAN) event_dev = vlan_dev_real_dev(event_dev); - cdev = cxgbi_device_find_by_netdev(event_dev, NULL); + cdev = cxgbi_device_find_by_netdev_rcu(event_dev, NULL); if (!cdev) return ret; -- cgit v1.1
