should "create_proc_read_entry" enforce read-only semantics?

["Robert P. J. Day" <rpjday@mindspring.com>]

  admittedly more nitpickery, but it strikes me as a bit confusing
that you can use create_proc_read_entry() to create writable proc
files, since that routine is simply a wrapper for create_proc_entry
that passes the mode untouched and unexamined.

  that's why you can get stuff like this from drivers/scsi/scsi_proc.c

...
        p = create_proc_read_entry(name, S_IFREG | S_IRUGO | S_IWUSR,
                        sht->proc_dir, proc_scsi_read, shost);
        if (!p) {
                printk(KERN_ERR "%s: Failed to register host %d in"
                       "%s\n", __FUNCTION__, shost->host_no,
                       sht->proc_name);
                return;
        }

        p->write_proc = proc_scsi_write_proc;
...

  it just seems to abuse the semantics to use a routine called
"create_proc_read_entry" to create a writable file.  but that's just
me.
