This series makes me happy. We've been talking about this conversion for a while and I'm thankful that you did this work. Without the automation available this probably wouldn't have happened as quickly as it did now. Let's see what bits and pieces it missed. --- Applied to the vfs-7.1.kino branch of the vfs/vfs.git tree. Patches in the vfs-7.1.kino branch should appear in linux-next soon. Please report any outstanding bugs that were missed during review in a new review to the original patch series allowing us to drop it. It's encouraged to provide Acked-bys and Reviewed-bys even though the patch has now been applied. If possible patch trailers will be updated. Note that commit hashes shown below are subject to change due to rebase, trailer updates or similar.
