Hi Matthew,
Thank you very much for your feedback. This patch looks straight-forward
enough, but do we need the filesystem maintainers to review this as
well? I guess we should CC the linux-ext4 and linux-xfs mailing lists in
the next revision.
Hi Ralph,
Are you OK if we update your patch with this suggestion?
Thanks,
Felix
