Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue.git master
commit f4a3e90ba5739cfd761b6befadae9728bd3641ed
Author: Phil Sutter <phil@nwl.cc>

rhashtable-test: extend to test concurrency
After having tested insertion, lookup, table walk and removal, spawn a
number of threads running operations on the same rhashtable. Each of
them will:
1) insert it's own set of objects,
2) lookup every successfully inserted object and finally
3) remove objects in several rounds until all of them have been removed,
making sure the remaining ones are still found after each round.
This should put a good amount of load onto the system and due to
synchronising thread startup via two semaphores also extensive
concurrent table access.
The default number of ten threads returned within half a second on my
local VM with two cores. Running 200 threads took about four seconds. If
slow systems suffer too much from this though, the default could be
lowered or even set to zero so this extended test does not run at all by
default.

Hi,
(Full-quoting here due to added maling lists.)
Looks like this is a problem of slow systems. I will try to reproduce

other tasks to be scheduled in large lookup loops").
Thanks for reporting,
Phil

Hi,
(Full-quoting here due to added maling lists.)
Looks like this is a problem of slow systems. I will try to reproduce

other tasks to be scheduled in large lookup loops").
Thanks for reporting,
Phil
