[KJ] Status of TODO item jiffies towards end

I am new at this but am very keen to contribute.  I 
thought I would start at the end of the TODO on the 
web site (hoping noone else thought of the same thing) 
and see what happens.

The item:

Some drivers do:

        if ((jiffies - data->last_updated > HZ * 2) ||
            (jiffies < data->last_updated))

Should be:

        #include <linux/jiffies.h>
        if (time_after(jiffies, data->last_updated + HZ * 2))

Have a patch for drivers/i2c/chips/*.

It seems this has been fixed because I only found the 
problem code in drivers/i2c/chips/* in kernel source 2.6.10.

Are there any items that need attention that it is known that 
noone is working on?  What kernel tree should I be looking at?

Yes, many of these have been fixed. Marcelo Parisi has been posting a
number of patches to KJML recently (check archives).

I'm not sure there is any way to verify this without asking about
specific TODO entries. As far as a tree to base on, it's always
whatever current mainline is (2.6.12-rc3 currently).

Thanks,
