[PATCH v2 0/3] lib/raid6: Optimize raid6_select_algo while ensuring

From: sunliming <[email protected]>

The selection of RAID6 PQ functions involves a dual-strategy approach:
prioritizing startup speed leads to quickly choosing a usable algorithm,
while prioritizing performance leads to selecting an optimal algorithm
via benchmarking. This choice is determined by the RAID6_PQ_BENCHMARK
configuration. This patch series achieves both fast startup and optimal
algorithm selection by initially choosing an algorithm quickly at startup,
then asynchronously determining the optimal algorithm through benchmarking.
Since all RAID6 PQ function algorithms are functionally equivalent despite
performance differences, this approach should be effective.

Changes in v2:
  Select the highest-priority algorithm instead of the first one. 
  Add the cancel_work_sync function in the exit function to handle the 
work queue cleanup.
instead of the first one.
