From 1252b283aae2b131f6d38fdff8792dfe9d4a536e Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 18 Sep 2023 09:58:10 -0400 Subject: [PATCH] NFSD: Add nfsd4_encode_fattr4_lease_time() Refactor the encoder for FATTR4_LEASE_TIME into a helper. In a subsequent patch, this helper will be called from a bitmask loop.
