Share config response may contain the share name without casefolding as it is known to the user space daemon. When it is present, casefold and compare it to the share name the share config request was made with. If they differ, we have a share config which is incompatible with the way share config caching is done. This is the case when CONFIG_UNICODE is not set, the share name contains non-ASCII characters, and those non- ASCII characters do not match those in the share name known to user space. In other words, when CONFIG_UNICODE is not set, UTF-8 share names now work but are only case-insensitive in the ASCII range.
