[PATCH v2] target:Fix target hung at iscsit_close_session()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This fixed an issue where IO stress testing on
top of OCFS2 over an iSCSI target. Missed a
complet operation caused the target hung,
requiring a reboot. Also moved the complete
operation out of the conditionals.
