[PATCH bpf-next 0/2] Documentation/bpf: Fix stale references in map docs

[Ahmad Wicaksono <supersonix03@gmail.com>]

Two documentation fixes for the BPF map pages.

Patch 1 records that since commit be39165224d0 ("bpf, sockmap: Disallow
update and delete from tc, xdp, socket_filter and flow_dissector"), only
BPF_TRACE_ITER tracing, sock_ops (delete only), sk_reuseport and
sk_lookup programs may mutate a sockmap or sockhash; anything else is
rejected with "cannot update sockmap in this context". The kernel-side
sections of map_sockmap.rst did not mention this. It also drops the
reference to progs/test_sockmap_update.c, removed by
commit 5de7a6eaed89 ("selftests/bpf: Drop
tc/xdp/flow_dissector/socket_filter sockmap mutation tests").

Patch 2 fixes two moved selftests paths: test_lpm_map.c, now
map_tests/lpm_trie_map_basic_ops.c, and test_xdp_noinline.c, now under
progs/.

Documentation only; no functional change.

checkpatch.pl --strict is clean. make SPHINXDIRS=bpf htmldocs gives
identical warnings before and after. Documentation only, so nothing to
run-test.
