60 memcpy  - memory copy between a source and a destination buffer
61 memset  - fill a destination buffer with a byte value
62 xor     - xor a series of source buffers and write the result to a
64 xor_val - xor a series of source buffers and set a flag if the
67 pq	- generate the p+q (raid6 syndrome) from a series of source buffers
68 pq_val  - validate that a p and or q buffer are in sync with a given series of
70 datap	- (raid6_datap_recov) recover a raid6 data block and the p block
72 2data	- (raid6_2data_recov) recover 2 raid6 data blocks from the given

94 manage the channel.  Once a driver-specific threshold is met the driver
95 automatically issues pending operations.  An application can force this
97 channels since the application has no knowledge of channel to operation
101 There are two methods for an application to learn about the completion
