In the 3 new 'split' readdir tests added by this patch, directory entries are retrieved, split over several Treaddir requests by picking small 'count' parameters which force the server to truncate the response. So the test client sends as many Treaddir requests as necessary to get all directory entries. The following 3 new tests are added (executed in this sequence): 1. Split readdir test with count=3D512 2. Split readdir test with count=3D256 3. Split readdir test with count=3D128 This test case sequence is chosen because the smaller the 'count' value, the higher the chance of errors in case of implementation bugs on server side.
