Subject: pNFS/flexfiles: Check the result of nfs4_pnfs_ds_connect
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=260f32adb88dadfaac29f47f761a088238ca164c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

pNFS/flexfiles: Check the result of nfs4_pnfs_ds_connect

The check in nfs4_ff_layout_prepare_ds() seems to be missing.
