Hi Alexey, Thank you for the patch! Yet something to improve: [auto build test ERROR on linux/master] [also build test ERROR on lwn/docs-next linus/master v5.5-rc3 next-20191220] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Alexey-Gladkov/proc-modernize-proc-to-support-multiple-private-instances/20191226-060818 base: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git 1522d9da40bdfe502c91163e6d769332897201fa config: i386-tinyconfig (attached as .config) compiler: gcc-7 (Debian 7.5.0-3) 7.5.0 reproduce: # save the attached .config to linux build tree make ARCH=i386 If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp@xxxxxxxxx> All error/warnings (new ones prefixed by >>): ld: init/do_mounts.o: in function `proc_fs_pid_gid': >> do_mounts.c:(.text+0x5): multiple definition of `proc_fs_pid_gid';
