As opposed to adding special cases to the kernel which are unswappable and stand to tangle up bits of the generic vfs - eg we would have a vma with a vm_file but that file would not be in the dcache ?
Is it really worth it. For temporary files unix has never adopted a tmpfile() syscall because nobody has ever found mkstemp() a paticularly critical path that justified it - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
