A patch [1] has been merged upstream. So, this bug can be proposed for rhgs-3.4.0

Comment 4 Raghavendra G 2017-09-04 06:31:54 EDT 
The test case is basically checking whether getdents on 3.4.0 returns more number of dentries compared to the baseline version - say rhgs-3.3.0. We can also compare with getdents on local fs.
