[PATCH] knfsd: nfsd4: pass saved and current fh together into nfsd4 operations
Pass the saved and current filehandles together into all the nfsd4 compound
operations.
I want a unified interface to these operations so we can just call them by
pointer and throw out the huge switch statement.
Also I'll eventually want a structure like this--that holds the state used
during compound processing--for deferral.
