Subject: [PATCH bpf-next v2 4/5] selftests/bpf: rename bpf_fentry_test{7,8,9} to bpf_fentry_test_ptr*
From: Menglong Dong <imagedong@...cent.com>
To make it more clear, let's make the N in bpf_fentry_testN as the count
of target function arguments. Therefore, let's rename
bpf_fentry_test{7,8,9} to bpf_fentry_test_ptr{1,2,3}.
Meanwhile, to stop the checkpatch complaining, move the "noinline" ahead
of "int".
