+michaelpg@ who is converting the device settings section (which includes the
storage overlay) to the MD Settings, slated for M54. We will probably need to
integrate these metrics into md-settings.

[fukino, 2016-07-20 16:36:58]

I've just started working on porting storage manager to MD settings for M54.
https://bugs.chromium.org/p/chromium/issues/detail?id=629438
I'll add metrics to MD settings as a part of porting.

This CL is only about old settings.
I'm going to ask a merge of this for M53, so I'd like to have this CL reviewed
separately.

[stevenjb, 2016-07-20 16:51:36]

I see, OK. lgtm then.

FYI: I update an issue that was created to discuss the conversion of metrics to
md-settings which has been languishing but clearly needs to be considered soon
(like now): http://crbug.com/604830

[fukino, 2016-07-20 17:06:12]

Thank you!
I'll watch the issue and follow the strategy to port UMA metrics.
