Subject: NFS: Set FATTR4_WORD0_TYPE for . and .. entries
X-Git-Tag: v4.13-rc2~10^2~46
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=18fe6a23e3114a6737471570753b708ff293b9de;p=platform%2Fkernel%2Flinux-exynos.git

NFS: Set FATTR4_WORD0_TYPE for . and .. entries

The current code worked okay for getdents(), but getdents64() expects
the d_type field to get filled out properly in the stat structure.
Setting this field fixes xfstests generic/401.
