Subject: [PATCH 2/8] selftests: livepatch: test-kprobe: Replace true/false mod param by 1/0
Date: Fri, 13 Mar 2026 17:58:33 -0300	[thread overview]
Message-ID: <20260313-lp-tests-old-fixes-v1-2-71ac6dfb3253@suse.com> (raw)
In-Reply-To: <20260313-lp-tests-old-fixes-v1-0-71ac6dfb3253@suse.com>

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 1/0 so the test module can be loaded on older kernels.

No functional changes.
