Hi Fengguang / LKP-folk,
Quick question -- how easy is it to add extra builds/tests/checks to
your marvellous 0-day kbuild system?
The reason I ask is that I've recently been exploring syzkaller ,
which is a system call fuzzer written by some of my colleagues here at
Google (cc'ed). Although it's fairly new, it has uncovered a bunch of
kernel bugs already  so I wondered if it might be a good candidate
for inclusion in the 0-day checks at some point.
(As an aside, I'm in the process of writing an article about syzkaller
for LWN, which might also expose it to more folk.)
What do you think?
FYI, we noticed a +12.6% improvement of vm-scalability.throughput due to commit:
commit 133e89ef5ef338e1358b16246521ba17d935c396 ("locking/rwsem: Enable lockless waiter wakeup(s)")
in testcase: vm-scalability
on test machine: lkp-bdw-ex2: 160 threads Broadwell-EX with 512G memory
with following parameters: cpufreq_governor=performance/runtime=300s/test=small-allocs-mt
