Subject: [PATCH v3] mac80211: use DECLARE_EVENT_CLASS
Date: Wed, 26 Jan 2011 09:22:15 +0100 [thread overview]
Message-ID: <1296030135.3635.11.camel@jlt3.sipsolutions.net> (raw)
In-Reply-To: <20110125215810.GE2927@tuxdriver.com>
From: Johannes Berg <johannes.berg@intel.com>
For events that include only the local struct as
their parameter, we can use DECLARE_EVENT_CLASS
and save quite some binary size across segments
as well lines of code.
text data bss dec hex filename
375745 19296 916 395957 60ab5 mac80211.ko.before
367473 17888 916 386277 5e4e5 mac80211.ko.after
-8272 -1408 0 -9680 -25d0 delta
Some more tracepoints with identical arguments
could be combined like this but for now this is
the one that benefits most.

v3: fix compile w/o mac80211 events -- I had forgotten
we have a "manual override" in that case
