Patch series "Cleanup and fixup for mm/migrate.c", v3. This series contains cleanups to remove unnecessary VM_BUG_ON_PAGE and rc != MIGRATEPAGE_SUCCESS check. Also use helper function to remove some duplicated codes. What's more, this fixes potential deadlock in NUMA balancing shared exec THP case and so on. More details can be found in the respective changelogs. This patch (of 5): The putback_movable_page() is just called by putback_movable_pages() and we know the page is locked and both PageMovable() and PageIsolated() is checked right before calling putback_movable_page(). So we make it static and remove all the 3 VM_BUG_ON_PAGE().

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.
