Thank you for the feedback. I am glad you like YAFFS.

To look at the bugs you report:

Thany you for explaining this problem - it caused me many hours of grief. 
However, in the last check in I went away from this way of doing things, so 
this patch no longer applies.

If you are using older code, then this will help.

Some people have looked at the latest code and commented that YAFFS returns 
NULL at this point. This **looks** wrong, but is in fact correct.

Please keep up the good detective work!
