Applied to the kernel-7.4.signal branch of the vfs/vfs.git tree. Patches in the kernel-7.4.signal 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.
