This patch attempts to standardize the naming of those most important (declared not defined) context structs. The present practice represents a hodge podge of names only some of which reflect the source /proc file name. And 2 of those file names embed a literal 'info' which is likely the origin of that required parm identifier. Now we'll append a universal '_info' to such structure names, while including the names of those /proc pseudo files where possible. In any case, that context struct will *always* begin with the actual module/header file name. And only the following two sound a little weird! ---------> 'meminfo_info' + 'slabinfo_info' <--------- Signed-off-by: Jim Warner <james.warner@comcast.net>
