Of particular note:
- Disable broken WRITE SAME support in all targets except linear and striped.
Use it when kcopyd is zeroing blocks.
- Remove several mempools from targets by moving the data into the bio's new
front_pad area(which dm calls 'per_bio_data').
- Fix a race in thin provisioning if discards are misused.
- Prevent userspace from interfering with the ioctl parameters and
use kmalloc for the data buffer if it's small instead of vmalloc.
- Throttle some annoying error messages when I/O fails.
