+AD4 Hm, I'm not sure why you're seeing that error (I'm not). We define
+AD4 pthread+AF8-rwlock+AF8-trywlock() in:
+AD4 
+AD4 	include/liblockdep/rwlock.h:static inline int liblockdep+AF8-pthread+AF8-rwlock+AF8-trywlock(liblockdep+AF8-pthread+AF8-rwlock+AF8-t +ACo-lock)
+AD4 
+AD4 All the tests also seem to pass for me. Did you see failures on your
+AD4 end?

What I saw is that due to the typo that is fixed by this patch that linking
of the tests failed and that the error message that was reported because
starting the tests failed made the tests pass due to the following line in
run+AF8-tests.sh:

if +AFs +ACQ(timeout 1 ./lockdep ./tests/+ACQ-testname 2+AD4AJg-1 +AHw wc -l) -gt 0 +AF0AOw then
