I think the same comment by dewittj@ at
https://codereview.chromium.org/2839703003/diff/1/chrome/browser/android/offl...

also applies here.

Switched to no explicit priority. Priority will be inherited from the calling
context. This is appropriate for code that may be used in different contexts.

   Profile* profile = Profile::FromBrowserContext(context);
   base::FilePath queue_store_path =
       profile->GetPath().Append(chrome::kOfflinePageRequestQueueDirname);
