From 9aeaf8cfcb71f3663737bc21b93da7e1b8845c0d Mon Sep 17 00:00:00 2001 From: Olga Kornievskaia Date: Thu, 6 Dec 2018 11:10:36 -0500 Subject: [PATCH] NFSv4.2 fix async copy reboot recovery Original commit (e4648aa4f98a "NFS recover from destination server reboot for copies") used memcmp() and then it was changed to use nfs4_stateid_match_other() but that function returns opposite of memcmp. As the result, recovery can't find the copy leading to copy hanging.
