Panda,

My impression from that ticket was you had a patch in mind - Is that the case?

Looks like everything has landed for 2.13 now

[James A Simmons]

Will this be back ported to 2.12. Seems LU-11359 fixes is dependent on this patch.

The LTS12 label means that it is flagged for inclusion on b2_12
