Microsoft WSL2 kernel modifications

If you want to dig into: for now it seems all to be HyperV related. I maybe wrong since I haven’t reviewed the code itself.

It’s based on the next 5.4.x kernel – probably since Ubuntu Focal also has 5.4 on LTS.

Improvement: Diff the original commit list with WSL source

cd wsl2
git fetch origin
git pull --unshallow 
cat ../files.txt \
    | xargs -I @ git log --follow --pretty="%h - %s" -- @ \
    | tee /dev/stderr | sort -u \
    > ../commits.txt

(improvement: or maybe output author as well)

Get all commits with HyperV (improvement: or sort by author)
sort -u ../commits.txt | rg -i 'hyper(-)?v' | sed -r 's|([a-f0-9]+) - |\1\t|g' | sort -k2 | tee ../hyperv-commits.txt
