If anyone has any objections, please let me know. ------------------ From: Sven Schnelle [ Upstream commit d22c3e0088e85be8131f7a9283f759cdbb20726d ] The current regex also matches symbols in modules, which makes the test fail on s390 where name_show is present only once in the kernel, but also multiple times in modules: 000001b1401cdc20 t name_show 000001b0c05e6c40 t name_show [mdev] 000001b0c0495f30 t name_show [i2c_core] Fix this by changing the regular expression to only match the function name.
