From: Mathieu Desnoyers Date: Fri, 17 May 2019 14:01:36 +0000 (-0400) Subject: Cleanup: bitfields: streamline use of underscores X-Git-Tag: v2.11.0-rc5~12 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=bf6a783825b46345d8f4616d47e12f0bcd2ce89d;p=lttng-modules.git Cleanup: bitfields: streamline use of underscores Do not prefix macro arguments with underscores. Use one leading underscore as prefix for local variables defined within macros.
