+Current BUGS 
+	Bug with opening a file with a name of 1,000,000 char long with no errors.
 
-	bug when trying to use yaffs_access on an existing file with mode 255 the error returned is EACCES it should be EINVAL(note there is no quick test file yet).
+	Bug with unlinking a file with 1,000,000 get the error ENOENT but should

-	WARNING- If yaffs is unmounted then most functions return ENODIR.
+	Bug with mounting a too long non-existant mount point is returning 
+	ENODEV. there are two errors here, ENOENT and ENAMETOOLONG.
+	The ENODEV is the error which yaffs gives instead of ENOENT.
+	BBut the mount function should just return ENAMETOOLONG.
 
+	Bug when mounting a non-existing mount point. The error code returned is 
+	ENODEV.
+
+	Bug when trying to use yaffs_access on an existing file with mode 255 
+	the error returned is EACCES it should be EINVAL(note there is no quick test file yet).
+
+	Bug when trying to access a non-existing directory the error ENOENT is 
+	returned. It should be ENOTDIR.
+
+	Bug when trying to truncate a file in a non-existing directory. The error
+	returned is ENOENT it should be ENOTDIR.
+
+	Bug truncating a file to a size of -1 does not cause an error. 
+
+
+Current WARNINGS
+	WARNING- If yaffs is unmounted then most of yaffs' functions return ENODIR. 
+	some function return EBADF instead.
+
+	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.
