The current subpage support in v5.18 has several limits, the most
obvious ones are:
- Only support 64KiB page size
- No RAID56 support
The supports are already queued for v5.19.
And some minor ones:
- No inline extent write support
Read is always supported.
Subpage mount will always just act as "max_inline=0".
- Compression write is only for page aligned range.
Read is always supported, no matter the alignment.
- Extra memory usage for scrub
Patchset is hanging there for a while though.
