[PATCH v3 11/16] bpfilter: Move bpfilter_umh back into init data

From: Eric W. Biederman <hidden>
Date: 2020-07-02 16:49:09
Also in: bpf, linux-fsdevel, lkml
Subsystem: networking [general], the rest · Maintainers: "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

To allow for restarts 61fbf5933d42 ("net: bpfilter: restart
bpfilter_umh when error occurred") moved the blob holding the
userspace binary out of the init sections.

Now that loading the blob into a filesystem is separate from executing
the blob the blob no longer needs to live .rodata to allow for restarting.
So move the blob back to .init.rodata.
