This is a method name but it hasn't been renamed in code. Did you test this?

[Jialiu Lin, 2016/07/20 19:05:33]

Yes, tested on Mac build. dismissMaliciousDownload is an existing function:
https://cs.chromium.org/chromium/src/chrome/browser/ui/cocoa/download/downloa...

[Robert Sesek, 2016/07/20 19:57:58]

Right, I was expecting dismissMaliciousDownload: to either be renamed in the
.h/mm file or removed. It looks like the XIB was the only caller.

[Jialiu Lin, 2016/07/20 20:05:59]

Oops, mistake in my previous reply. I actually meant "discardDownload" is an
existing function. 
And you're right, "dissmissMaliciousDownload" function is no longer needed.
Removed it from download_item_controller.h/mm
