Since sed doesn't like multi-line make sure all EXPORT_SYMBOL_NS
things are a single line.

Eww.  Just use coccinelle or another tool not so simplistic.

Feel free to do so. I've never managed to get coccinelle to do anything.

So I put a little more effort in and got you this (awk needs to be
gawk>=4.1)

git grep -l -e MODULE_IMPORT_NS -e EXPORT_SYMBOL_NS | while read file;
do
  awk -i inplace '
    /^#define EXPORT_SYMBOL_NS/ {
      gsub(/__stringify\(ns\)/, "ns");
      print;
      next;
    }
    /^#define MODULE_IMPORT_NS/ {
      gsub(/__stringify\(ns\)/, "ns");
      print;
      next;
    }
    /MODULE_IMPORT_NS/ {
      $0 = gensub(/MODULE_IMPORT_NS\(([^)]*)\)/, "MODULE_IMPORT_NS(\"\\1\")", "g");
    }
    /EXPORT_SYMBOL_NS/ {
      if ($0 ~ /(EXPORT_SYMBOL_NS[^(]*)\(([^,]+),/) {
        if ($0 !~ /(EXPORT_SYMBOL_NS[^(]*)\(([^,]+), ([^)]+)\)/ &&
            $0 !~ /(EXPORT_SYMBOL_NS[^(]*)\(\)/ &&
            $0 !~ /^my/) {
          getline line;
          gsub(/[[:space:]]*\\$/, "");
          gsub(/[[:space:]]/, "", line);
          $0 = $0 " " line;
        }

        $0 = gensub(/(EXPORT_SYMBOL_NS[^(]*)\(([^,]+), ([^)]+)\)/,
                    "\\1(\\2, \"\\3\")", "g");
      }
    }
    { print }' $file;
done


I'm sure that wasn't worth the time I spend on it though :/
