Subject: [PATCH 0/2] fix two bugs for file THP

Patch 1/2 had been sent about weeks ago, the original
link here:
https://patchwork.kernel.org/project/linux-mm/patch/20211011022241.97072-2-rongwei.wang@linux.alibaba.com/
It seems to be ignored, and send out again here.

Patch 2/2 is sent out first time. And Patch 1/2 and
2/2 both to fix different bugs for commit
eb6ecbed0aa2 ("mm, thp: relax the VM_DENYWRITE constraint on file-backed
THPs").

In addition, I find the stable version (I had check 5.14) has contained
above commit (eb6ecbed0aa2), so I will add "cc stable mail list"
when sending Patches.

Thanks!
