[LTP] [PATCH 1/1] lib: Add LTP_ENABLE_DEBUG to doc

[Petr Vorel]

Hi,

> https://lore.kernel.org/ltp/20250515103146.14950-1-chrubis@suse.cz/

And that is exactly the reason why patch fails to build in CI
(patch is not applicable without Cyril's patch).

Here is the verification this simple patch does not fail to build:
https://github.com/pevik/ltp/actions/runs/15053601640

Kind regards,
