I think it would be relatively simple and sane to modify the existing kmap() implementations to add a new try_kmap() which is atomic and returns failure if it would have needed to sleep. That being said, kmap() is a sort of old and deprecated thing which scales badly on SMP. We've put considerable work into moving over to kmap_atomic() and using nice tight short code regions where atomic kmappings are held. - 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/
