Linus Torvalds 37b33c68b0 CRC updates for 6.14
- Reorganize the architecture-optimized CRC32 and CRC-T10DIF code to be
   directly accessible via the library API, instead of requiring the
   crypto API.  This is much simpler and more efficient.
 
 - Convert some users such as ext4 to use the CRC32 library API instead
   of the crypto API.  More conversions like this will come later.
 
 - Add a KUnit test that tests and benchmarks multiple CRC variants.
   Remove older, less-comprehensive tests that are made redundant by
   this.
 
 - Add an entry to MAINTAINERS for the kernel's CRC library code.  I'm
   volunteering to maintain it.  I have additional cleanups and
   optimizations planned for future cycles.
 
 These patches have been in linux-next since -rc1.
