Hi Yang,
Thank you for the patch! Yet something to improve:

If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <l...@intel.com>
All errors (new ones prefixed by >>):
arch/s390/mm/gmap.c: In function 'thp_split_mm':
arch/s390/mm/gmap.c:2498:27: error: 'FOLL_SPLIT' undeclared (first use in this
function); did you mean 'FOLL_PIN'?
2498 | follow_page(vma, addr, FOLL_SPLIT);

| FOLL_PIN
arch/s390/mm/gmap.c:2498:27: note: each undeclared identifier is reported
only once for each function it appears in
vim +2498 arch/s390/mm/gmap.c
There appears to be an imperfection in this 0day testing system, because (just
as the patch
says), commit ba925fa35057a062ac98c3e8138b013ce4ce351c ("s390/gmap: improve THP
splitting"),
July 29, 2020, removes the above use of FOLL_SPLIT.
And "git grep", just to be sure, shows it is not there in today's linux.git. So
I guess the
https://github.com/0day-ci/linux repo needs a better way to stay in sync?
thanks,
