Subject: [PATCH v1 1/1] ACPI: processor: idle: Replace strlcat() with better alternative
Date: Mon, 16 Mar 2026 18:01:58 +0100 [thread overview]
Message-ID: <20260316170158.1596857-1-andriy.shevchenko@linux.intel.com> (raw)
strlcpy() and strlcat() are confusing APIs and the former one already gone
from the kernel. In preparation to kill strlcat() replace it with the better
alternative.
