raid6: hide internals

2026-05-29T04:24:54+00:00

Split out two new headers from the public pq.h:

 - lib/raid/raid6/algos.h contains the algorithm lists private to
   lib/raid/raid6
 - include/linux/raid/pq_tables.h contains the tables also used by
   async_tx providers.

The public include/linux/pq.h is now limited to the public interface for
the consumers of the RAID6 PQ API.

raid6: improve the public interface

2026-05-29T04:24:54+00:00

Stop directly calling into function pointers from users of the RAID6 PQ
API, and provide exported functions with proper documentation and API
guarantees asserts where applicable instead.

treewide: use get_random_bytes() when possible

2022-10-11T23:42:58+00:00

The prandom_bytes() function has been a deprecated inline wrapper around
get_random_bytes() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function. This was done as a basic find and replace.
