Hi folks,
I recently started seeing spurious test failures with rbtree tests,
resulting in boot delays and random "hung task" warnings.
The problems have been fixed upstream with the following patches.
v4.14.y:
0b548e33e6cb lib/rbtree-test: lower default params
v4.4.y, v4.9.y:
a54dae0338b7 lib/interval_tree_test.c: make test options module parameters
c46ecce431eb lib/interval_tree_test.c: allow full tree search
Wait, this patch breaks the build for 4.4.y and 4.9.y, so this isn't
going to work well:
lib/interval_tree_test.c: In function ‘interval_tree_test_init’:
lib/interval_tree_test.c:105:38: error: ‘max_endpoint’ undeclared (first use in this function); did you mean ‘tracepoint’?
unsigned long last = search_all ? max_endpoint : queries[j];
^~~~~~~~~~~~
tracepoint
So I'm going to drop these from the 4.4 and 4.9 and 3.18 trees. How did they
build for you?
I had also applied commit a8ec14d4f6aa8e ("lib/interval_tree_test.c: allow users
to limit scope of endpoint") and for some reason dropped that from my e-mail.
Sorry :-(.
