From 9a837856cf612d83e9ede7081972a2fa78de6921 Mon Sep 17 00:00:00 2001 From: Fred Isaman Date: Tue, 27 Sep 2016 15:37:11 -0400 Subject: [PATCH] NFSv4.1: Fix regression in callback retry handling When initializing a freshly created slot for the calllback channel, the seq_nr needs to be 0, not 1. Otherwise validate_seqid and nfs4_slot_wait_on_seqid get confused and believe that the mpty slot corresponds to a previously sent reply.
