Recently boot parameter 'debug_boot_weak_hash' was added. Latter discussion on LKML developed more descriptive documentation but due to the programmers lack of understanding (*cough* me) on how linux-next works these improvements never got picked up.
Update documentation for boot parameter 'debug_boot_weak_hash' as discussed (patch posted and acked) on LKML.
