Subject: [RFC lockdep 0/4] Fixes and self testcases for wait context detection
Date: Tue, 8 Dec 2020 18:31:08 +0800 [thread overview]
Message-ID: <20201208103112.2838119-1-boqun.feng@gmail.com> (raw)
Hi Peter,
Recently I looked into the wait context check feature and found some
places could use fixes, besides a suite of test cases is also added to
verify these fixes and future development.
Note: I'm not 100% sure all the expected results of the test cases are
correct, please do have a look at the the comment of patch #4 in case I
miss something subtle.
Suggestion and comments are welcome!
Regards,
Boqun
