-
-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.
