That is not safe as you could get interrupted between the two calls and something else might have already grabbed the region you thought was free by the time you get to calling request_region(). So, request_region() was rewritten to do the checking internally and let the caller know via its return value if acquiring the region failed or succeded. So these days check_region should no longer be used. It's a historic relic. request_region() should be used directly instead. That's why it is deprecated. -- Jesper Juhl <[EMAIL PROTECTED]> Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please http://www.expita.com/nomime.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
