This patch triggers non-blocking busy poll when busy_poll is enabled,
epoll is called with a timeout of 0 and is associated with a napi_id.
This enables an app thread to go through napi poll routine once by
calling epoll with a 0 timeout.
poll/select with a 0 timeout behave in a similar manner.

Two RED qevents have been introduced recently. From the point of view of a

Previously, shared blocks were only relevant for the pseudo-qdiscs ingress

Adding support to generate .BTF_ids section that will hold BTF
ID lists for verifier.
Adding macros that will help to define lists of BTF ID values
placed in .BTF_ids section. They are initially filled with zeros
(during compilation) and resolved later during the linking phase
by resolve_btfids to
Adding resolve_btfids test under test_progs suite.
It's possible to use btf_ids.h header and its logic in
user space application, so we can add easy test for it.
The test defines BTF_ID_LIST and checks it gets properly
resolved.
For this reason the test_progs binary (and other binaries
that use
Now when we moved the helpers btf_id arrays into .BTF_ids section,
we can remove the code that resolve those IDs in runtime.

hi,
this patchset does preparation work for adding d_path helper,
which still needs more work, but the initial set of patches
is ready and useful to have.
This patchset adds:

kernel linking and usable within kernel code with followi

This way the ID is resolved during compile time,
and we can remove the runtime name search.

The resolve_btfids tool scans elf object for .BTF_ids section
and resolves its symbols with BTF ID values.
It will be used to during linking time to resolve arrays of BTF
ID values used in verifier, so these IDs do not need to be
resolved in runtime.
The expected layout of .BTF_ids section is des
It will be needed by bpf selftest for resolve_btfids tool.
Also adding __PASTE macro as btf_ids.h dependency, which is
defined in:
include/linux/compiler_types.h
but because tools/include do not have this header, I'm putting
the macro into linux/compiler.h header.

S
Using BTF_ID_LIST macro to define lists for several helpers
using BTF arguments.
And running resolve_btfids on vmlinux elf object during linking,
so the .BTF_ids section gets the IDs resolved.

Rationale:
Documentation/arm/ixp4xx.rst contains "xdp" as part of "ixdp465"
