The RAID problem (which is caused by VM changes) is the same deadlock
found in drbd and nbd.

It was not a problem with kernels < 2.2.17 because there was no write
throttling in shrink_mmap.

I'm attaching "raid-0.90-2.2.17.patch" and "raid-2.2.17.patch". They
should fix, respectively, raid 0.90 and stock 2.2.17 raid.

I haven't tested the patches.
