Clarify that paralell direct can only be enabled where the kernel version supports it, which is 6.2+. State the two cache.files modes which can support parallel direct writes in the description.
This makes it clear, along with the previous commit, that per-process will allow us to use parallel direct writes as they will mount with the equivalent of cache.files=off (i.e. direct_io)
Change which 'comm' name -> whose 'comm' name. Whose implies possession, and the process possess the name we're matching

Brill, I was tempted to drop direct_io mentions in the section initially but didn't want to go ahead without that feedback. |

Clarifies some points around cache.files and parallel-direct-writes. See commit messages for details:
Tl;dr:
parallel-direct-writes- Steer people to usecache.files=offinstead ofdirect_io- Clarify which eachcache.filesimplies, so people with existing mount options can (hopefully) say, I can consolidate my mount flags intocache.files=foocache.files=offis the process name does not match
