@miked-mellanox That's a false jenkins failure, right?

[mike-dubman]

yep, i just added jenkins job for "master" but forgot to change url.
sorry.

[jladd-mlnx]

@rhc54 @hppritchard I think this should be signed off on by Howard before it's merged. It should also be added to the 1.8.4 release notes.

[hjelmn]

Looks good to me.

[hjelmn]

@jladd-mlnx this was discussed already at lanl and howard and I agreed this was the way to go for now

[rhc54]

I will be sure it gets into the NEWS as well.

[jladd-mlnx]

@rhc54 thanks!

[hjelmn]

@jladd-mlnx I should mention the fix for message coalescing can be found here: hjelmn/ompi@db84aa9
