arcmsr_iop_message_xfer() is called from atomic context under the
queuecommand scsi_host_template handler. James Bottomley pointed out
that the current GFP_KERNEL|GFP_DMA flags are wrong: firstly we are in
atomic context, secondly this memory is not used for DMA.
Also removed some unneeded casts.

ioc->name is used in the printk's after ioc has been freed. Free
after prinks to fix this.
This patch fixes two use-after-free's introduced by
commit e78d5b8f1e73ab82f3fd041d05824cfee7d83a2c and spotted by the

The spinlock is held over too large a region: pscratch is a permanent
address (it's allocated at boot time and never changes). All you need
the smp lock for is mediating the scratch in use flag, so fix this by
moving the spinlock into the case where we set the pscratch_busy flag
to false.

The panic occurs if we get a MSGIN or MSGOUT for an unidentified SCB
(meaning we didn't identify the outstanding command it was for). For
MSGIN this is wrong because it could be an unsolicited negotiation
MSGIN from the target.
Still panic on unsolicited MSGOUT because this would represent a
mistake in the negotiation phases. However, we should fix this as
well. The specs say we should go to bus free for unexpected msgin.

scsi_debug does at several places:
for_each_sg(sdb->table.sgl, sg, sdb->table.nents, k) {
kaddr = (unsigned char *)
kmap_atomic(sg_page(sg), KM_USER0);
We cannot do something like that with the clustering enabled (or we

This driver has been failing under heavy load with
aic94xx: escb_tasklet_complete: REQ_TASK_ABORT, reason=0x6
aic94xx: escb_tasklet_complete: Can't find task (tc=4) to abort!
The second message is because the driver fails to identify the task
it's being asked to abort. On closer inpection, there's a thinko in
the for each task loop over pending tasks in both the REQ_TASK_ABORT
and REQ_DEVICE_RESET cases where it doesn't look at the task on the
pending list but at the one on the ESCB (which is always NULL).
Fix by looking at the right task. Also add a print for the case where
the pending SCB doesn't have a task attached.
Not sure if this will fix all the problems, but it's a definite first
step.

2. preserve len for page1
3. need to move desc_ptr even the entry is not enclosure_component_device/raid.
so keep desc_ptr on right position
4. record page7 len, and double check if desc_ptr out of boundary before touch.
5. fix typo in subenclosure checking: should use hdr_buf instead.

This is the central patch of a cleanup series. In most cases there is no good
reason why someone would want to use a dentry for itself. This series reflects
that fact and embeds a struct path into nameidata.
Together with the other patches of this series
- it enforced the correct order of getting/releasing the reference count on
<dentry,vfsmount> pairs
- it prepares the VFS for stacking support since it is essential to have a
struct path in every place where the stack can be traversed
- it reduces the overall code size:

There's an undesirable interaction with issuing MRA requests to
increase connection timeouts and the listen backlog.
When the rdma_cm receives a connection request, it queues an MRA with
the ib_cm. (The ib_cm will send an MRA if it receives a duplicate
REQ.) The rdma_cm will then create a new rdma_cm_id and give that to
the user, which in this case is the rdma_user_cm.
If the listen backlog maintained in the rdma_user_cm is full, it
destroys the rdma_cm_id, which in turns destroys the ib_cm_id. The
ib_cm_id generates a REJ because the state of the ib_cm_id has changed
to MRA sent, versus REQ received. When the backlog is full, we just
want to drop the REQ so that it is retried later.
Fix this by deferring queuing the MRA until after the user of the
rdma_cm has examined the connection request.

mlx4_table_find (for FMR MPTs) requires that ICM memory already be
mapped. Before this fix, FMR allocation depended on ICM memory
already being mapped for the MPT entry. If all currently mapped
entries are taken, the find operation fails (even if the MPT ICM table
still had more entries, which were just not mapped yet).
This fix moves the mpt find operation to fmr_enable, to guarantee that
any required ICM memory mapping has already occurred.

Currently mlx4_ib_fmr_alloc() calls mlx4_mr_enable() instead of

this is not really correct (and the change is needed to fix a bug).

In P_Key event handling, if the old P_Key is no longer available, the
driver must call ipoib_ib_dev_stop() -- just as it does when the P_Key
is still available (see procedure __ipoib_ib_dev_flush()).
When a P_Key becomes available, the driver will perform ipoib_open(),
which assumes that the QP is in RESET, the cm_id has been
destroyed/deleted, etc. If ipoib_ib_dev_stop() is not called as
described above, then these assumptions will be false, and the attempt
to bring the interface up will fail.
