Jinshan,
Would you please have a look and comment on this one?

[James A Simmons]

Is this observed any more?

[Jinshan Xiong (Inactive)]

I think this problem has been fixed in some patch. James, are you still seeing this?

[James A Simmons]

The reason I ask is that I was looking at LU-4011 and wanted to see what fixed this bug (LU-4489) and if it was in the upstream lustre client for the kernel so LU-4011 could be close.

[James A Simmons]

I haven't seen this bug in ages. Time to close this ticket.

[Peter Jones]

Yes. Likely fixed during CLIO Simplification (if not before)
