Merge branch 'bpf-xdp-add-tracepoint-to-xdp-attaching-failure'
Leon Hwang says:
====================
bpf, xdp: Add tracepoint to xdp attaching failure
This series introduces a new tracepoint in bpf_xdp_link_attach(). By
this tracepoint, error message will be captured when error happens in
dev_xdp_attach(), e.g. invalid attaching flags.
v4 -> v5:
* Initialise the extack variable.
* Fix code style issue of variable declaration lines.
v3 -> v4:
* Fix selftest-crashed issue.
====================
