BUG:using__this_cpu_add_return()in_preemptible[#]code:test_progs
Greeting,
FYI, we noticed the following commit (built with gcc-9):
commit: a9945c7bb7ffedbff64637915753eaa6cf21335d ("[PATCH] bpf: Fix recursion check in trampoline")
url: https://github.com/0day-ci/linux/commits/Jiri-Olsa/bpf-Fix-recursion-check-in-trampoline/20210428-064239
base: https://git.kernel.org/cgit/linux/kernel/git/bpf/bpf-next.git master
in testcase: kernel-selftests
version: kernel-selftests-x86_64-cf9ae1bd-1_20210401
with following parameters:
group: bpf
ucode: 0xde
test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt
on test machine: 4 threads 1 sockets Intel(R) Core(TM) i7-7567U CPU @ 3.50GHz with 32G memory
