Probably once you start writing a patch you will figure it out. :) keymap_store() is a crap function. We have the cp1 pointer that points to the end of two back to back 3 char arrays. The name cp1 is because it is the second copy of the cp buffer which is a copy of the buf buffer. Since it is a backwards array we use cp1[-3] where normally we would say array[0] and cp1[-1] to mean the last element in the array.
We need around 6 characters in cp1, but we are only garaunteed to have 2. There is no checking. Lots of checkpatch.pl warnings. Just focus on cleaning up keymap_store() and hopefully at the end you can just delete spk_s2uchar(). regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
