25 # Runtime vlog is used everywhere except on ash-chrome.
26 # Ash-chrome has a few vmodule patterns that need to be used indefinitely
27 # to investigate problems from logs in feedback reports. These vmodule
28 # patterns are using too much cpu cycles (see http://crbug/489441). Turning
29 # off runtime vlog and using build time vlog would avoid paying that cpu tax
30 # and have a nice side effect of a smaller production binary.
