2007-03-01[PATCH] md: add support for reshape of a raid6NeilBrown1-33/+124
i.e. one or more drives can be added and the array will re-stripe while on-line. Most of the interesting work was already done for raid5. This just extends it to raid6. mdadm newer than 2.6 is needed for complete safety, however any version of mdadm which support raid5 reshape will do a good enough job in almost all cases (an 'echo repair > /sys/block/mdX/md/sync_action' is recommended after a reshape that was aborted and had to be restarted with an such a version of mdadm).

2007-03-01[PATCH] md: restart a (raid5) reshape that has been aborted due to a ↵NeilBrown2-29/+47
read/write error An error always aborts any resync/recovery/reshape on the understanding that it will immediately be restarted if that still makes sense. However a reshape currently doesn't get restarted. With this patch it does. To avoid restarting when it is not possible to do work, we call into the personality to check that a reshape is ok, and strengthen raid5_check_reshape to fail if there are too many failed devices. We also break some code out into a separate function: remove_and_add_spares as the indent level for that code was getting crazy.

one device md tries to warn the user if they e.g. create a raid1 using two partitions of the same device, as this does not provide true redundancy. However it also warns if a raid0 is created like this, and there is nothing wrong with that. At the place where the warning is currently printer, we don't necessarily know what level the array will be, so move the warning from the point where the device is added to the point where the array is started.

2007-03-01[PATCH] md: fix raid10 recovery problem.NeilBrown1-18/+20
There are two errors that can lead to recovery problems with raid10 when used in 'far' more (not the default). Due to a '>' instead of '>=' the wrong block is located which would result in garbage being written to some random location, quite possible outside the range of the device, causing the newly reconstructed device to fail. The device size calculation had some rounding errors (it didn't round when it should) and so recovery would go a few blocks too far which would again cause a write to a random block address and probably a device error. The code for working with device sizes was fairly confused and spread out, so this has been tided up a bit.

2007-02-28[PATCH] x86_64/i386 irq: Fix !CONFIG_SMP compilationEric W. Biederman2-6/+0
When removing set_native_irq I missed the fact that it was called in a couple of places that were compiled even when SMP support is disabled. And since the irq_desc[].affinity field only exists in SMP things broke. Thanks to Simon Arlott <simon@arlott.org> for spotting this. There are a couple of ways to fix this but the simplest one is to just remove the assignments. The affinity field is only used to display a value to the user, and nothing on either i386 or x86_64 reads it or depends on it being any particlua value, so skipping the assignment is safe. The assignment that is being removed is just for the initial affinity value before the user explicitly sets it. The irq_desc array initializes this field to CPU_MASK_ALL so the field is initialized to a reasonable value in the SMP case without being set. Signed-off-by: Eric W.

To reproduce this panic consistently, we run an intensive network application like 'netperf'. After waiting for a couple of seconds, you will see a stack trace and a kernel panic where we are calling pci_unmap_single() in ql_poll(). Changes: 1) Check the flags on the Response MAC IO Control block to check for errors 2) Ensure that if we are on the 4022 we only use one segment 3) Before, we were reading the memory mapped producer index register everytime we iterated in the loop when clearing the queue.
