Hi Christophe,

I'm recently enhancing the subpage support for btrfs, and my current
branch should solve the problem for btrfs to support larger page sizes.

But unfortunately my current test environment can only provide page size
with 64K or 4K, no 16K or 128K/256K support.

Mind to test my new branch on 128K page size systems?
(256K page size support is still lacking though, which will be addressed
in the future)

The Linux Asahi folks have a 16K page environment (M1 Macs)...

Su Yue kindly helped me testing 16K page size, and it's pretty OK there.

So I'm not that concerned.

It's 128K page size that I'm a little concerned, and I have not machine
supporting that large page size to do the test.

Thanks,
Qu

Hector, could you look at it too?
