[PATCH v1 13/52] NFSD: Add nfsd4_encode_fattr4_lease_time()

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

 



From: Chuck Lever <chuck.lever@xxxxxxxxxx>

Refactor the encoder for FATTR4_LEASE_TIME into a helper. In a
subsequent patch, this helper will be called from a bitmask loop.
