master clients with 2.10.5 servers

 Description   

Recent landings to master have caused sanity-hsm tests 1b, 12c,f, g, h, m, o, p, 14, 15, 24a,b,d,e,f, 30b,c, 31b,c, 34, 35, 36, 37, 57, 58, 59, 110b, 222b,d, 223b, 228, 260c, 407 to fail for interop testing; master clients with 2.10.5 servers.

Looking at the failed test session at https://testing.whamcloud.com/test_sets/0de77f1c-e73e-11e8-b67f-52540065bddc , in the client 2 (vm6) console log, we see the following in most of the failed tests

[19290.833447] LustreError: 13720:0:(vvp_io.c:1495:vvp_io_init()) lustre: refresh file layout [0x200007936:0x6:0x0] error -61.

The above failure is for Lustre master 2.11.56.112 build #3824 clients and 2.10.5 servers. The last master build that we have interop test results for is for build #3821 and the testing passed. Nothing has landed to 2.10.5 for a couple of months. Thus, a patch causing this interop failure landed to master between builds #3821 and #3824.

This is what landed between build 3821 and 3824:

LU-11508 mdt: reject DoM file migration

LU-11380 mdc: move empty xattr handling to mdc layer

Revert "LU-8130 ptlrpc: convert conn_hash to rhashtable"

I think my change 0f42b38843 (LU-11380 mdc: move empty xattr handling to mdc layer) is the most likely culprit here.

Have you tried pushing a test to check this theory?
