Description

This issue was created by maloo for Quentin Bouget <[e-mail]>

This issue relates to the following test suite run: patch_for_lu-8911.

test_1a crashes the Client 2 on Maloo with a very low failure rate (<5%)
Following tests fail with "'/mnt/lustre2' not mounted" and eventually sanity-hsm times out.

There seems to be a race in libcfs_kkuc_group_put().

I currently don't have a method to reproduce.
