Add several BPF kselftest cases for tail calls which test the various patch directions, and that multiple locations are patched in same and different programs. # ./test_progs -n 45 #45/1 tailcall_1:OK #45/2 tailcall_2:OK #45/3 tailcall_3:OK #45/4 tailcall_4:OK #45/5 tailcall_5:OK #45 tailcalls:OK Summary: 1/5 PASSED, 0 SKIPPED, 0 FAILED I've also verified the JITed dump after each of the rewrite cases that it matches expectations. Also regular test_verifier suite passes fine which contains further tail call tests: # ./test_verifier [...] Summary: 1563 PASSED, 0 SKIPPED, 0 FAILED Checked under JIT, interpreter and JIT + hardening.
