[PATCH v3] Documentation: test.h - fix warnings

by Lothar Rubusch

Fix warnings at 'make htmldocs', and formatting issues in the resulting documentation. - test.h: Fix some typos in kernel-doc parameter description. - Documentation/*.rst: Fixing formatting issues, and a duplicate label issue, since using sphinx.ext.autosectionlabel in conf.py, referes to headers are generated automatically and sphinx will not complain about identical headers among documents anymore. The downside is, automatically generated header labels within one document now cannot be overwritten manually anymore. Thus duplicate headers within one document have to have different wording, i.e. this patch modifies some headers. - Documentation/api/*: Flipping over to a page "API" containing a single link to another page "API" seems like a formatting issue. The patch removes one level of indirection. v2: Several documentation fixes v3: Do not touch API documentation index Signed-off-by: Lothar Rubusch <l.rubusch(a)gmail.com> --- Documentation/dev-tools/kunit/start.rst | 13 ++++++++----- Documentation/dev-tools/kunit/usage.rst | 4 ++-- include/kunit/test.h | 7 ++++--- 3 files changed, 14 insertions(+), 10 deletions(-) diff --git a/Documentation/dev-tools/kunit/start.rst b/Documentation/dev-tools/kunit/start.rst index e1c5ce80ce12..bb112cf70624 100644 --- a/Documentation/dev-tools/kunit/start.rst +++ b/Documentation/dev-tools/kunit/start.rst @@ -32,15 +32,17 @@ test targets as well.

i386: selftests: vm: compaction_test: BUG: kernel NULL pointer dereference, address: 00000000

by Naresh Kamboju

On Linux mainline kernel 5.6.0 running kselftest vm compaction_test on i386 kernel running on x86_64 devices we have noticed this Kernel BUG followed by Kernel panic.

[PATCH AUTOSEL 5.4 015/108] selftests/bpf: Fix test_progs's parsing of test numbers

by Sasha Levin

From: Andrii Nakryiko <andriin(a)fb.com> [ Upstream commit fc32490bff855a539d253c8a52c5a1ba51d1325a ] When specifying disjoint set of tests, test_progs doesn't set skipped test's array elements to false. This leads to spurious execution of tests that should have been skipped. Fix it by explicitly initializing them to false.
