    md/raid6: move raid6 data processing to raid6_pq.ko · f701d589
    Dan Williams authored
    Move the raid6 data processing routines into a standalone module
    (raid6_pq) to prepare them to be called from async_tx wrappers and other
    non-md drivers/modules.  This precludes a circular dependency of raid456
    needing the async modules for data processing while those modules in
    turn depend on raid456 for the base level synchronous raid6 routines.
    
    To support this move:
    1/ The exportable definitions in raid6.h move to include/linux/raid/pq.h
    2/ The raid6_call, recovery calls, and table symbols are exported
    3/ Extra #ifdef __KERNEL__ statements to enable the userspace raid6test to
       compile
