Hi Phil,
On m68k/ARAnyM, test_rhashtable fails with:
Test failed: thread 0 returned: -4
(-4 = -EINTR)
I traced this back to your commit f4a3e90ba5739cfd ("rhashtable-test: extend
to test concurrency"), which added that part of the test.
Diff of the test output between the failing commit and its parent:
Running rhashtable test nelem=8, max_size=65536, shrinking=0

Do you have any clue?
Thanks!
