This led to fuse_readdirp_cbk to wrongly think it has a valid stat (due to valid ia_gfid and ia_type) and give to kernel zeroed out attributes causing failures. Fix is included in <a href="https://review.gluster.org/20639">https://review.gluster.org/20639</a> to make sure to let kernel know attributes are not valid in this scenario (and not zero out stats even if inode picked up by readdirplus is not linked yet).</div><div><br></div><div>regards,</div><div>Raghavendra<br></div><div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Aug 13, 2018 at 6:12 AM, Shyam Ranganathan <span dir="ltr"><<a href="mailto:srangana@redhat.com" target="_blank">srangana@redhat.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">As a means of keeping the focus going and squashing the remaining tests<br>
