    nfsd4: teach encoders to handle reserve_space failures · d0a381dd
    J. Bruce Fields authored
    We've tried to prevent running out of space with COMPOUND_SLACK_SPACE
    and special checking in those operations (getattr) whose result can vary
    enormously.
    
    However:
    	- COMPOUND_SLACK_SPACE may be difficult to maintain as we add
    	  more protocol.
    	- BUG_ON or page faulting on failure seems overly fragile.
    	- Especially in the 4.1 case, we prefer not to fail compounds
    	  just because the returned result came *close* to session
    	  limits.  (Though perfect enforcement here may be difficult.)
    	- I'd prefer encoding to be uniform for all encoders instead of
    	  having special exceptions for encoders containing, for
    	  example, attributes.
