Modify list_push_pop_multiple to alloc and insert nodes 2-at-a-time. Without the previous patch's fix, this block of code: bpf_spin_lock(lock); bpf_list_push_front(head, &f[i]->node); bpf_list_push_front(head, &f[i + 1]->node); bpf_spin_unlock(lock); would fail check_reference_leak check as release_on_unlock logic would miss a ref that should've been released.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
