Panda,

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

Thanks, Cory.  Autoupdate from Gerrit must be acting up.

Looks like everything has landed for 2.13 now

Comment by James A Simmons [ 06/Jun/19 ]

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
