Build bots are generally nice, but in this case... pretty much all of
the changes are in fs/namei.c, which is not all that sensitive to
config/architecture/whatnot. Sure, something like "is audit enabled?"
may affect the build problems, but not much beyond that.

What was that Intel-run(?) bot that posts "such-and-such metrics has
42% regression on such-and-such commit" from time to time?
<checks>
Subject: [locking/qspinlock] 7b6da71157: unixbench.score 8.4% improvement
seems to be the latest of that sort,
From: kernel test robot <rong.a.chen@intel.com>

Not sure how much of pathwalk-heavy loads is covered by profiling
bots of that sort, unfortunately... ;-/
