In the current implementation unmap_and_move() would return -ENOMEM if THP migration is unsupported, then the THP will be split. If split is failed just exit without trying to migrate other pages. It doesn't make too much sense since there may be enough free memory to migrate other pages and there may be a lot base pages on the list. Return -ENOSYS to make consistent with hugetlb. And if THP split is failed just skip and try other pages on the list. Just skip the whole list and exit when free memory is really low.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
