Hi YueHaibing, Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on net-next/master] [also build test WARNING on v5.0-rc8 next-20190228] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system] url: https://github.com/0day-ci/linux/commits/Yue-Haibing/appletalk-Fix-use-after-free-in-atalk_proc_exit/20190228-195802 config: i386-randconfig-x003-201908 (attached as .config) compiler: gcc-8 (Debian 8.2.0-20) 8.2.0 reproduce: # save the attached .config to linux build tree make ARCH=i386 All warnings (new ones prefixed by >>): >> WARNING: net/appletalk/appletalk.o(.init.text+0x104): Section mismatch in >> reference from the function init_module() to the function >> .exit.text:atalk_proc_exit() The function __init init_module() references a function __exit atalk_proc_exit(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __exit annotation of atalk_proc_exit() so it may be used outside an exit section. --- 0-DAY kernel test infrastructure Open Source Technology Center https://lists.01.org/pipermail/kbuild-all Intel Corporation
