The raid6 recovery code currently requires special handling of the
4-disk and 5-disk recovery scenarios for the native layout. Quoting
from commit 0a82a623:
In these situations the default N-disk algorithm will present
0-source or 1-source operations to dma devices. To cover for
dma devices where the minimum source count is 2 we implement
4-disk and 5-disk handling in the recovery code.
The ddf layout presents disks=6 and disks=7 to the recovery code in
these situations. Instead of looking at the number of disks count the
number of non-zero sources in the list and call the special case code
when the number of non-failed sources is 0 or 1.
