The new library meminfo & vmstat modules use structure names for their context which exactly mirror the names of the very /proc/ files whose particulars they yield. The one exception to this rule was the readstat module whose struct was named statinfo yet the file was stat. This commit simply renames that structure (only) so as to hopefully establish such a naming convention as our standard going forward. And, it's makes good symmetry. [ this module's name itself is just perfect as it is ] Signed-off-by: Jim Warner <james.warner@comcast.net>
