Linux Patches Begin Adapting RAID Code To Use Folios

A new set of patches posted today to the Linux kernel mailing list begin adapting the Linux software RAID code paths to begin making use of the folio data structure.

Folios have continued to see continued usage throughout the Linux kernel since their merging back in 2021 with Linux 5.16. Folios allow more efficiently managing a groups of contiguous memory pages for better performance while often simplifying the kernel code too.
