Fan Yong (fan.yong@intel.com) uploaded a new patch: https://review.whamcloud.com/26079
Subject: LU-9224 fid: race between client_fid_fini and seq_client_flush
Project: fs/lustre-release
Branch: master
Current Patch Set: 1
Commit: d7959890967eaca7d0a6076622d5e2f3d015fa5d
When client mount failure or umount, the client_fid_fini() will be called. At that time, the async connection failure will trigger seq_client_flush(). Unfortunately the parameter for seq_client_flush() may be released by client_fid_fini() by race
