Subject: [PATCH] selftests/x86/lam: Zero out buffer for readlink()
Date: Sun, 24 Sep 2023 07:33:46 +0800 [thread overview]
Message-ID: <20230923233346.12726-1-binbin.wu@linux.intel.com> (raw)
Zero out the buffer for readlink() since readlink() does not append a
terminating null byte to the buffer.
Fixes: 833c12ce0f430 ("selftests/x86/lam: Add inherit test cases for linear-address masking")
