Subject: os: A stream for debug logging.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=270279ac997e2a7b4e57c122b8ae217195271f72;p=mesa.git

os: A stream for debug logging.

Just a wrapper around os_log_message. Although it would probably make
more sense to be the other way around.

Also some comment fixes.
