+ Bug with opening a file with bad mode. yaffs_open has two modes which
+ are passed into it. if the modes are set to 255 the open function
+ does not report any errors. (Also need to try this with modes set to -1.)
+
+ Bug with lseeking to a very large size (size =100000000000000000000000000000000000000) without causing an error.
+ Should cause the error EINVAL.
