NFSv4.2 fix async copy reboot recovery
Original commit (e4648aa4f9
"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. Fixes:80f4236886
("NFSv4: Split out NFS v4.2 copy completion functions") Fixes:cb7a8384dc
("NFS: Split out the body of nfs4_reclaim_open_state") Signed-of-by: Olga Kornievskaia <kolga@netapp.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
