Which version of gcc are you using? It doesn't print any error message for me on version 4.3.2 (which is really old). The idea is fine but the patch is all messed up. First of all the it's reversed. It says '+' where it should say '-' and '-' where it should say '+'. Also your mail client has completely mangled it. It has removed spaces from the start of lines and changed the tabs to spaces. Please read Documentation/email-clients.txt and send an email to yourself. Save the email as raw text. cat email.txt | patch -p1. When that works resend it. Add these people to the CC list: Mike Miller <mike.miller@xxxxxx> Jens Axboe <jaxboe@xxxxxxxxxxxx> "Stephen M. Cameron" <scameron@xxxxxxxxxxxxxxxxxx> iss_storagedev@xxxxxx Also you don't need to copy all 16 lines of error messages. Just a couple will do. But do say which version of gcc you are using. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
