[PATCH] nfsd: using nfsd4_encode_noop for encoding destroy_session/free_stateid

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Get rid of the extra code, using nfsd4_encode_noop for encoding destroy_session and free_stateid.
And, delete unused argument (fr_status) int nfsd4_free_stateid.
