mainline inclusion
from mainline-v6.8-rc1
commit e3b47e460b4bd0c61d0082f1ac02650dcb79e5d1
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I9VYQ9
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=e3b47e460b4bd0c61d0082f1ac02650dcb79e5d1



--------------------------------

This patch adds a selftest for userspace PM to remove the initial
subflow.

Use userspace_pm_add_sf() to add a subflow, and pass initial IP address
to userspace_pm_rm_sf() to remove the initial subflow.
