I think I had the same problem.
Another problem, maybe related to this one is:
   1.  Copy a file onto the yaffs directory.
   2.  Delete it.
   3.  Copy another file into the directory with the same name.
   4.  Delete it.
   => kernel oops due to an inode having a null parent.
When I add a flush method in file_operation that just call yaffs_FlushFile(),
my problem doesn't appear anymore AND yours does not happen.
