Subject: TREE_SRCU slows hotplug by factor ~16
Date: Mon, 24 Apr 2017 04:48:09 +0200 [thread overview]
Message-ID: <1493002089.4145.7.camel@gmx.de> (raw)
Greetings,
Running Steven's hotplug stress script in tip w. CLASSIC_SRCU takes 55s
in my i4790 box, whereas TREE_SRCU takes over 16m. (Master with the
same config does it in 39s.. but then lockdep isn't enabled in master)
-Mike
