ipod vfat

Dear Kernel Developers,

Is it possible to incorporate the next patch which I had to introduce to
have the vfat fs of my ipod to get mounted under Linux.

Originally its vfat was mounting ok, but then at some point which I
didn't clearly mentioned, it stopped... probably it happened after I
attached ipod to some windows box, because now windows still can easily
mount it whenever vanilla linux kernel refuses...

Or should I just adjust my ipod's fs definition?

Thank you in advance

I'm sorry guys - it seems that the necessary steps were taken in the
last kernel version:

        /*
         * The low byte of FAT's first entry must have same value with
         * media-field.  But in real world, too many devices is
         * writing wrong value.  So, removed that validity check.
         *
         * if (FAT_FIRST_ENT(sb, media) != first)
         */

So I will give it a spin :-)

Sorry once again
