Re: [PATCH v2] tracing: Allow changing default ring buffer size for ftrace instances.

ld go back to that though if you think that's okay, but I think your previous reasoning still makes sense: it's useful for the user to know if there will be an allocation failure before enabling tracing. What are your thoughts? Bharath Ravi | rbhar...@google.com On Fri, Apr 25, 2014

Re: [PATCH] tracing: Allow instances to have independent trace flags/trace options.

Hi Steven, This patch allows instances to have their own independent trace options (as opposed to the current globally shared trace options) Does this look like a reasonable change? Bharath Ravi | rbhar...@google.com On Fri, Nov 22, 2013 at 10:51 AM, Bharath Ravi wrote: > Currently,
