Add pid in all fuse ops

Hi @stapelberg , would appreciate some comments & feedback!

Adding the caller process id to all ops sounds okay to me in general, but:

1. Why do you need to disable writeback caching for the pid to become available?
2. Your pull request seems to contain a lot of unrelated commits? Can you clean it up please? (rebase)

Thanks,

Thanks for the review!

1. We disabled the writeback cache because when the write comes from the writeback cache, there is no pid associated with that (the test may be flaky as a result).
2. Rebased!

If the PR is squash-merged, then this is not relevant. right?

Cleanly separated commits also make the review easier, no matter if they end up in the git history or not :)
