The receive_fd_replace case shares almost no logic with the more general
__receive_fd case, so split it into a separate function.
BTW, I'm not sure if receive_fd_replace is such a useful primitive to
start with, why not just open code it in seccomp?
receive_fd_replace shares almost no code with the general case, so split
it out. Also remove the "Bump the sock usage counts" comment from
both copies, as that is now what __receive_sock actually does.

Hi,
You are missing to add these patches to linux-pm mailing list.
Need to send them to linu-pm ML.
Also, before received this series, I tried to clean-up these patches
on testing branch[1]. So that I add my comment with my clean-up case.

Hi,
I think that you can squash this patch to patch4.

To reduce assembly codes, let's merge duplicate codes into one
(xchg_acquire, xchg_release, cmpxchg_release).

riscv only support lr.wd/s(c).w(d) with word(double word) size &
align access. There are not lr.h/sc.h instructions. But qspinlock.c
need xchg with short type variable:
xchg_tail -> xchg_releaxed(>tail, ...
typedef struct qspinlock {
union {
atomic_t val;
