Subject: 5015a300a5 ("lib: introduce test_meminit module"): BUG: sleeping function called from invalid context at mm/page_alloc.c:4664
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://kernel.googlesource.com/pub/scm/linux/kernel/git/torvalds/linux.git master
commit 5015a300a522c8fb542dc993140e4c360cf4cf5f
Author: Alexander Potapenko <glider@...gle.com>
AuthorDate: Tue Jul 16 16:27:27 2019 -0700
Commit: Linus Torvalds <torvalds@...ux-foundation.org>
CommitDate: Tue Jul 16 19:23:22 2019 -0700
lib: introduce test_meminit module
Add tests for heap and pagealloc initialization. These can be used to
check init_on_alloc and init_on_free implementations as well as other
approaches to initialization.
Expected test output in the case the kernel provides heap initialization
(e.g. when running with either init_on_alloc=1 or init_on_free=1):
test_meminit: all 10 tests in test_pages passed
test_meminit: all 40 tests in test_kvmalloc passed
test_meminit: all 60 tests in test_kmemcache passed
test_meminit: all 10 tests in test_rcu_persistent passed
test_meminit: all 120 tests passed!
