[PATCH v4 bpf-next 15/17] selftests: xsk: remove thread attribute

From: Maciej Fijalkowski <maciej.fijalkowski@intel.com>
Date: 2021-03-26 23:22:21
Also in: bpf
Subsystem: bpf [general] (safe dynamic programs and tools), bpf [selftests] (test runners & infrastructure), kernel selftest framework, the rest, xdp (express data path) · Maintainers: Alexei Starovoitov, Daniel Borkmann, Andrii Nakryiko, Eduard Zingerman, Kumar Kartikeya Dwivedi, Shuah Khan, Linus Torvalds, David S. Miller, Jakub Kicinski, Jesper Dangaard Brouer, John Fastabend

From: Björn Töpel <redacted>

There is really no reason to have a non-default thread stack
size. Remove that.
