Hmmm... But, in failure case, is it safe to call putback_lru_page() for them?
And, PageIsolated() would be left. Is it okay? It's not symmetric that
isolated page can be freed by decreasing ref count without calling
putback function. This should be clarified and documented.
I agree

Apply mobile page migration into balloon driver.
The balloong driver has an anonymous inode that manages
address_space_operation for page migration.
Compaction calls interfaces of mobile page migration
instead of calling balloon migration directly.

which is probabyl why this patch series doesn't come with a user. Might be
better to first upstream the driver before talking about additional

Can the various in-kernel GPU drivers benefit from this? If so, wiring

I'm sure that other in-kernel GPU drivers can have benefit.

check more than 512MB is used with free command
- command balloon 512 in qemu monitor
- check hundreds MB of pages are migrated
Next kernel compaction code can call generic migration callbacks instead of
balloon driver interface.
Finally calling migration of balloon driver is removed.
