Subject: tree-wide: add DEBUG_LOGGING macro that checks whether debug logging is on (#7645)
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=7c81c217c26c10226c313a9b78b6aa685de9ccef;p=elogind.git

tree-wide: add DEBUG_LOGGING macro that checks whether debug logging is on (#7645)

This makes things a bit easier to read I think, and also makes sure we
always use the _unlikely_ wrapper around it, which so far we used
sometimes and other times we didn't. Let's clean that up.
