Description
There's a flurry of failures. In maloo it mostly fails in sanity-flr test 200, but I also saw it in racer at least once with a partially similar backtrace.

sample report: http://testing.linuxhacker.ru:3333/lustre-reports/1051/testresults/racer-ldiskfs-DNE-centos7_x86_64-centos7_x86_64 and in maloo: https://testing.whamcloud.com/test_sets/58251f94-a11a-11e9-8dbe-52540065bddc
This seems to be a very recent crash scenario too appearing just two das ago.
Coincidentally we just landed this patch n that timeframe: https://review.whamcloud.com/35111
So I guess it's the prime suspect now.
