Merge tag 'nfs-for-5.2-3' of git://git.linux-nfs.org/projects/anna/linux-nfs
Pull more NFS client fixes from Anna Schumaker: "These are mostly refcounting issues that people have found recently. The revert fixes a suspend recovery performance issue. - SUNRPC: Fix a credential refcount leak - Revert "SUNRPC: Declare RPC timers as TIMER_DEFERRABLE" - SUNRPC: Fix xps refcount imbalance on the error path - NFS4: Only set creation opendata if O_CREAT" * tag 'nfs-for-5.2-3' of git://git.linux-nfs.org/projects/anna/linux-nfs: SUNRPC: Fix a credential refcount leak Revert "SUNRPC: Declare RPC timers as TIMER_DEFERRABLE" net :sunrpc :clnt :Fix xps refcount imbalance on the error path NFS4: Only set creation opendata if O_CREAT
