From 33a1e6ea73e5f1defe6706f006c0930a82ebdaaa Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Sat, 23 Mar 2024 09:25:54 -0400 Subject: nfsd: trivial GET_DIR_DELEGATION support This adds basic infrastructure for handing GET_DIR_DELEGATION calls from clients, including the decoders and encoders. For now, it always just returns NFS4_OK + GDD4_UNAVAIL. Eventually clients may start sending this operation, and it's better if we can return GDD4_UNAVAIL instead of having to abort the whole compound.
