[PATCH v2 2/6] selftests: livepatch: Replace true/false module parameter by y/n

Marcos Paulo de Souza
2026-04-13T17:26:28Z

Older kernels don't support true/false for boolean module parameters
because they lack commit 0d6ea3ac94ca
("lib/kstrtox.c: add "false"/"true" support to kstrtobool()"). Replace
true/false by y/n so the test module can be loaded on older kernels.

No functional changes.
