This is a snapshot of my -mm patch queue. Uploaded at random hopefully
more than once a week.
You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY). The series file is in broken-out.tar.gz and is duplicated in
https://ozlabs.org/~akpm/mmotm/series
The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss. Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.
On i386:
../mm/damon/vaddr.c: In function ‘damon_hugetlb_mkold’:
../mm/damon/vaddr.c:402:17: warning: unused variable ‘h’ [-Wunused-variable]
struct hstate *h = hstate_vma(vma);
Ah, thanks for report, I think below changes can fix the warning. And
I'll send a new version to address this warning.
