+ Bug with lseeking to a very large size (size =100000000000000000000000000000000000000) without causing an error.
+ Should cause the error EINVAL.

+
+ Bug when writing a file. The writing to the file causes the file size to exceed the size of yaffs file system memory.
+ Output of test:

+Current WARNINGS
+
+ WARNING- If yaffs is unmounted then most of yaffs' functions return ENODIR.
+ But some function return EBADF instead.
+ Functions which return ENOTDIR: open, close, access, unlink, lseek, write, read
+
+ Functions which return ENOENT: access, stat
+
+
+
+ WARNING-the function yaffs_open does not check the mode passed to it.
+ This means that yaffs open does not return EINVAL if a bad mode is passed to it.
+ However this causes the error EEXIST to happen instead, because both O_CREAT and O_EXCL flags are set.
+
+ WARNING- yaffs_open will work with either of the two mode set to 255.
+ However there are only 4 or 5 flags that can be set for each of the modes.
+ This means that the programmer may not be setting the flags properly.
+
+ WARNING- When mounting a non-existing mount point the error ENODEV is returned.
+ The quick tests have been altered to accommodate this error code.
+ With standard access function in linux the error returned is ENOENT.
