lib/raid6/test: fix multiple definition linking error GCC 10+ defaults to -fno-common, which enforces proper declaration of external references using "extern". without this change a link would fail with: lib/raid6/test/algos.c:28: multiple definition of `raid6_call'; lib/raid6/test/test.c:22: first defined here the pq.h header that is included already includes an extern declaration so we can just remove the redundant one here.

raid6/test/test.c: bug fix: Specify aligned(alignment) attributes to the char arrays Specifying the aligned attributes to the char data[NDISKS][PAGE_SIZE], char recovi[PAGE_SIZE] and char recovi[PAGE_SIZE] arrays, so that all malloc memory is page boundary aligned. Without these alignment attributes, the test causes a segfault in userspace when the NDISKS are changed to 4 from 16. The RAID stripes will be page aligned anyway, so we want to test what the kernel actually will execute. Cc: H.

md/raid6 algorithms: improve test program It is always helpful to have a test tool in place if we implement new data critical algorithms. So add some test routines to the raid6 checker that can prove if the new xor_syndrome() works as expected. Run through all permutations of start/stop pages per algorithm and simulate a xor_syndrome() assisted rmw run. After each rmw check if the recovery algorithm still confirms that the stripe is fine.
