Merge tag 'nfs-for-5.2-4' of git://git.linux-nfs.org/projects/anna/linux-nfs 

Pull two more NFS client fixes from Anna Schumaker:
 "These are both stable fixes.

  One to calculate the correct client message length in the case of
  partial transmissions. And the other to set the proper TCP timeout for
  flexfiles"

* tag 'nfs-for-5.2-4' of git://git.linux-nfs.org/projects/anna/linux-nfs:
  NFS/flexfiles: Use the correct TCP timeout for flexfiles I/O
  SUNRPC: Fix up calculation of client message length
