prov/gni: plug race condition in rma get path #1418

Closed hppritcha closed 6 years ago

hppritcha commented 6 years ago

There was a race condition in the rma get path for unaligned source buffers. There was an atomic dec followed by an atomic read. This leads to a race condition when using the GNI provider in multi-threaded conditions.
