Baptiste Lepers 5ab7612ff0 pnfs/flexfiles: Fix misplaced barrier in nfs4_ff_layout_prepare_ds ... [ Upstream commit a2915fa062 ] _nfs4_pnfs_v3/v4_ds_connect do some work smp_wmb ds->ds_clp = clp; And nfs4_ff_layout_prepare_ds currently does smp_rmb if(ds->ds_clp) ... This patch places the smp_rmb after the if. This ensures that following reads only happen once nfs4_ff_layout_prepare_ds has checked that data has been properly initialized.
