Both patches with LU-977 fix - https://review.whamcloud.com/28075 and
without LU-977 fix - https://review.whamcloud.com/28168 have been pushed.
Test requires some higher number of OSTs and clients to be reproduced, tested with 73 OSTs and 44 client - 100 % reproducible.
Test passed with fix on (max available env.) 66 clients(11 mounted clients on 6 nodes) and 24 OSTs(3 OSS) - https://testing.hpdd.intel.com/sub_tests/5e9ca542-6c95-11e7-8cd2-5254006e85c2.
