Paulo Motta commented on CASSANDRA-10580:
-----------------------------------------

bq. can you please confirm if that's what everyone follows ?

You're generating patch correctly. I suspect you're not on the correct branch. 
Is your cassandra-2.2 head b03ce9fd479d3da9c51d118c50480ea96df0d73e ?

If not, you need to synchronize your git repo with 
https://github.com/apache/cassandra.git and checkout the latest cassandra-2.2 
branch, and build your patch on the top of it.

bq. About the tests, I don't think the failures are related to my change. Are 
those failures expected ?

I think they are unrelated too, they're in pair with main branch failures:

> In our production cluster, we are seeing a large number of dropped mutations. 
> At a minimum, we should print the time the thread took to get scheduled 
> thereby dropping the mutation (We should also print the Message / Mutation so 
> it helps in figuring out which column family was affected). This will help 
> find the right tuning parameter for write_timeout_in_ms. 
> The change is small and is in StorageProxy.java and MessagingTask.java. I 
> will submit a patch shortly.
