# Use runtime vlog everywhere except for ash-chrome.
# When `use_runtime_vlog` is true,
# command line switch `--vmodule=xxx` or `--v=x` could be used to
# control vlog level at runtime.
# when `use_runtime_volog` is false,
# verbose log level is controlled by `ENABLE_VLOG_LEVEL` macro. VLOG(n)
# is kept and generate output if `n` is less than or equal to the vlog
# level defined by the macro.
# Command line switch `--vmodule=xxx`, or `--v=x` would have no effect.

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