Hi all, When looking into "Failures: generic/467" given by xfstests, I found that NFSv3 didn't implement LOOKUPP. I know that this might be by design. But LOOKUPP was meant to replace ".." in NFSv3, right? xfstests's generic/467 test case performs the following sequence of operations. name_to_handle -> drop_caches -> open_by_handle Dentry becomes disconnected due to drop_caches. NFSv3 doesn't support LOOKUPP. So when it performs open_by_handle to an directory, this test case fails. I did some small experiment by implementing LOOKUPP for NFSv3. The way I tried is to merely pass ".." to nfs3_proc_lookup. And it seems to work. At least it's a workaround for xfstests. I'm curious whether this sort of simulation of LOOKUPP will work or make sense. Thanks, Yihao Wu
