commit d243b89a611e83dc97ce7102419360677a664076 upstream.
Some of the xfs error message functions take a pointer to a buffer that
will be dumped to the system log. The logging functions don't change
the contents, so constify all the parameters. This enables the next
patch to ensure that we log bad metadata when we encounter it.
