Behavior of ftrace_modify_code_2r() is similar to ftrace_modify_code_2(),
just the order of modification changed. Add a new struct ftrace_insn
to combine ftrace_modify_code with above two functions. The function is
same with the original ftrace_modify_code when ftrace_insn.code[1]
is DONT_SET.

Hi,
I would like to send a signal from a bpf program invoked from a
perf_event. There is:
// kernel/trace/bpf_trace.c
BPF_CALL_1(bpf_send_signal_thread, u32, sig)
which is nice, but it does not allow me to pass any arguments.
I can use a bpf map indexed by pid to "pass" some additional info, but

There are multiple similar bugs implicitly introduced by the

commit 6a2c0962105ae8ce ("vsock: prevent transport modules unloading").
The bug pattern:

pool_page_reusable() is a leftover from pre-NUMA-aware times. For now,
this function is just a redundant wrapper over page_is_pfmemalloc(),
so inline it into its sole call site.
