When doing an unexpected shutdown like kexec the cciss firmware might still have some commands in flight, which it is trying to complete. The driver is doing it's best on resetting the HBA, but sadly there's a firmware issue causing the firmware _not_ to abort or drop old commands. So the firmware will send us commands which we haven't accounted for, causing the driver to panic. With this patch we're just ignoring these commands as there is nothing we could be doing with them anyway. Signed-off-by:

This fixes kernel.org bug #13584. The IOVA code attempted to optimise the insertion of new ranges into the rbtree, with the unfortunate result that some ranges just didn't get inserted into the tree at all. Then those ranges would be handed out more than once, and things kind of go downhill from there. Introduced after 2.6.25 by ddf02886 ("PCI: iova RB tree setup tweak"). Signed-off-by:

We can run a 32-bit kernel on boxes with an IOMMU, so we need pci_unmap_addr() etc. to work -- without it, drivers will leak mappings. To be honest, this whole thing looks like it's more pain than it's worth; I'm half inclined to remove the no-op #else case altogether. But this is the minimal fix, which just does the right thing if CONFIG_DMAR is set. Signed-off-by:

This minimal patch removes that yielding stuff and adds the proper cond_resched(). The background scanning thread could probably also be reniced to +10.

The next_ordered flag is only meaningful for devices that use __make_request. So move the test against next_ordered out of generic code and in to __make_request Since this test was added, barriers have not worked on md or any devices that don't use __make_request and so don't bother to set next_ordered. (dm explicitly sets something other than QUEUE_ORDERED_NONE since commit 99360b4c but notes in the comments that it is otherwise meaningless).

This patch restores stacking ability to the block layer integrity infrastructure by creating a set of dedicated bip slabs. Each bip slab has an embedded bio_vec array at the end. This cuts down on memory allocations and also simplifies the code compared to the original bvec version. Only the largest bip slab is backed by a mempool. The pool is contained in the bio_set so stacking drivers can ensure forward progress. Signed-off-by:

Setup an emergency fallback cfqq that we allocate at IO scheduler init time. If the slab allocation fails in cfq_find_alloc_queue(), we'll just punt IO to that cfqq instead. This ensures that cfq_find_alloc_queue() never fails without having to ensure free memory. On cfqq lookup, always try to allocate a new cfqq if the given cfq io context has the oom_cfqq assigned. This ensures that we only temporarily punt to this shared queue. Reviewed-by:

User space can set various limits on an md array so that resync waits when it gets to a certain point, or so that I/O is blocked for a short while. When md is waiting against one of these limit, it should use an interruptible wait so as not to add to the load average, and so are not to trigger a warning if the wait goes on for too long.

This reverts commit 73ce7b01. After discovering that we don't listen to gratuitious arps in 2.6.30 I tracked the failure down to this commit. The patch makes absolutely no sense. RFC2131 RFC3927 and RFC5227. are all in agreement that an arp request with sip == 0 should be used for the probe (to prevent learning) and an arp request with sip == tip should be used for the gratitous announcement that people can learn from. It appears the author of the broken patch got those two cases confused and modified the code to drop all gratuitous arp traffic. Ouch! Cc: stable@kernel.org Signed-off-by:
