Hi Ferruh,

Yes, it was my mistake I was little late while pushing patches. Actually these patches are for 19.05 release.
If it not bother you, could you please merge these patches to 19.05? otherwise I'll mark title to 19.08.

Thanks,

Got it, only there already patches on the backlog waiting from rc1 which sent
the patch on time, they will be the priority otherwise it will be unfair to
them, and I will work on this with best effort for 19.05.

Hi Gagandeep,

Since the patchset has been sent after RC1, I assume it is for 19.08. Can you
please mark patch title as 19.08 to not confuse with current release?
