From 40116ebd0934cca7e46423bdb3397d3d27eb9fb9 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 17 Nov 2020 09:50:23 -0500 Subject: NFSD: Add helper to set up the pages where the dirlist is encoded De-duplicate some code that is used by both READDIR and READDIRPLUS to build the dirlist in the Reply. Because this code is not related to decoding READ arguments, it is moved to a more appropriate spot.
