From 0a8f37fb34a96267c656f7254e69bb9a2fc89fe4 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 10 Nov 2020 10:24:39 -0500 Subject: NFSD: Fix returned READDIR offset cookie Code inspection shows that the server's NFSv3 READDIR implementation handles offset cookies slightly differently than the NFSv2 READDIR, NFSv3 READDIRPLUS, and NFSv4 READDIR implementations, and there doesn't seem to be any need for this difference. As a clean up, I copied the logic from nfsd3_proc_readdirplus().
