* NOTES:
* None of these errno will ever be set by the Jehanne kernel.
* It's possible however that a file server designed to mimic a Unix
* behaviour use them.
*
* The value 1 is reserved since -1 is the default return value of

*
* The constant values are continuous, thus ERRNO_FIRST and ERRNO_LAST
* can be used to create a map from errors to descriptions.
