Jeremy Hanna commented on CASSANDRA-8584:
-----------------------------------------

So pre-logback, all of this would go into the output.log because that's where 
stderr goes.  I presume it's the same for logback.  The output.log never rolls 
on a running server.  Not sure if that affects how we handle this, but just 
wanted to make sure it wouldn't fill up the volume eventually.

> Since trySkipCache returns an errno rather than -1 and setting errno like our 
> other CLibrary calls, it's thread-safe and we could print out more helpful 
> information if we failed to prompt the kernel to skip the page cache.  That 
> system call should always succeed unless we have an invalid fd as it's free 
> to ignore us.
