Subject: Re: [PATCH v3 6/8] mm/zsmalloc: add __init,__exit attribute

Hi,

[auto build test WARNING on next-20160705]
[cannot apply to tip/perf/core v4.7-rc6 v4.7-rc5 v4.7-rc4 v4.7-rc6]
[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/Ganesh-Mahendran/mm-zsmalloc-use-obj_index-to-keep-consistent-with-others/20160706-150030
config: i386-randconfig-a0-201627 (attached as .config)
compiler: gcc-6 (Debian 6.1.1-1) 6.1.1 20160430
reproduce:
        # save the attached .config to linux build tree
        make ARCH=i386 

All warnings (new ones prefixed by >>):

>> WARNING: mm/built-in.o(.init.text+0x4c3f): Section mismatch in reference from the function zs_init() to the function .exit.text:zsmalloc_unmount()
   The function __init zs_init() references
   a function __exit zsmalloc_unmount().
   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
   zsmalloc_unmount() so it may be used outside an exit section.
