Hi Linus,

Here's a final batch of EFI fixes for v6.14. The efivarfs ones are fixes for
changes that were made this cycle. James's fix is somewhat of a band-aid, but
it was blessed by the VFS folks, who are working with James to come up with
something better for the next cycle.

Please pull.

The following changes since commit e3cf2d91d0583cae70aeb512da87e3ade25ea912:
