My local arm64 host has 64KB page size and the VM to run test_progs
also has 64KB page size. There are a few self tests assuming 4KB page
and failed in my environment.
Patch 1 reduced long assert logs so if the test fails, developers
can check logs easily. Patches 2-4 fixed three selftest failures.
Changelogs:
v2 -> v3:
- v2: https://lore.kernel.org/bpf/20250606174139.3036576-1-yonghong.song@xxxxxxxxx/
- Fix veristat failure with bpf object file test_ringbuf_write.bpf.o.
v1 -> v2:
- v1: https://lore.kernel.org/bpf/20250606032309.444401-1-yonghong.song@xxxxxxxxx/
- Fix a problem with selftest release build, basically from
BUILD_BUG_ON to ASSERT_LT.
