- for __xlated() it is commit 68ec5395bc24, backport of mainline commit
a41b3828ec05 ("selftests/bpf: Verify that sync_linked_regs preserves
subreg_def")
- for netlink_helper-related error " netlink_helpers.h: No such file or
directory", is should be commit e41db26543ef backport of mainline
commit 5f1d18de7918 ("selftests/bpf: Extend tcx tests to cover late
tcx_entry release")
For __xlated() I think we just need a refresh patch that removes its
use, the test cases should function without it albeit at a reduced
coverage.
OTOH for netlink_helper it's probably simpler to have it backported
(note: there was the precedence of b02372814ad6, but that's related to
netkit, which was not in 6.6, where as tcx is in 6.6).
I'll send a new series which the proposed changes.
