[cdwg] [wc-discuss] Lustre 2.2.0 released

[Peter Jones]

Alexey

I am sorry if my explanation was not clear enough.

The decision was taken to not classify this as a blocker because the 
issue only occurs when running kernel debug options.

The engineers in the triage process considered this not to be a common 
scenario for production usage.

As such it was decided it would be better to have the release be on time 
for the majority and know that anyone needing to run kernel debug 
options would be able to apply a simple patch to do so.

The kind of logic applied to determining blockers for Lustre releases 
has been unchanged for many years.

Regards

Peter
