This patch set adds a number of new tests to the test_bpf.ko test suite. The tests are intended to verify the correctness of eBPF JITs. Changes since v2: * Fixed tail call test case to handle the case where a called function is outside the 32-bit range of the BPF immediate field. Such calls are now omitted in this test. (13/13) * Fixed typo in commit message.
