    2 reasons:

    This change will eventually isolate multiple line
    printk messages and allow easier insertion of


    so that multiple line messages are kept together
    in the message logs.

    and I've done tree-wide patches for single line


    (about 2000) and fixed several dozen lines without \n
    or things like "KERN_<level> /n msg"

    Here's the perl script I used.

    It's imperfect of course. There are comments with
    embedded semicolons where it fails, and #defines
    aren't substituted too well.

    if ($#ARGV < 2) {
    print "usage: KERN_<level> pr_<level> files...\n";

    for ($i=2; $i <= $#ARGV; $i++) {
    PrintkSearchReplace($ARGV[$i], $ARGV[0], $ARGV[1]);

    sub PrintkSearchReplace{
    my($file, $search, $replace) = @_;

    my $orig = "";
    open(my $fh, $file) or die "File not found '$file'\n";
    $orig = <$fh>;
    close(my $fh);

    my $parts = $orig;
    my $whole = "";
    @segments = split(/\;/, $parts);
    foreach $line (@segments) {

    if ($whole ne "") {
    $whole = $whole . "\;";

    my $origline = $line;

    if ($line =~ m/\bprintk\s*\(\s*${search}\s*.*\".*\\n\s*\"/ms) {

    $line =~ s/\bprintk\s*\(\s*${search}\s*([^\"]*)\"/${replace}\(\1\"/ms;
    $line =~ s/\\n\s*\"\s*/\"/ms;

    print "${file}: changed:\n" . $origline . "\;" . "\nto:\n" . $line . "\;" . "\n" ;

    $whole = $whole . $line;

    if ($orig ne $whole) {
    open(my $fh, ">${file}") or die "Could not open '$file'\n";
    print $fh $whole;
    close(my $fh);
