The linux-next integration testing tree
b91f94729d
Patch series "transfer page to folio in KSM". This is the first part of page to folio transfer on KSM. Since only single page could be stored in KSM, we could safely transfer stable tree pages to folios. This patchset could reduce ksm.o 57kbytes from 2541776 bytes on latest akpm/mm-stable branch with CONFIG_DEBUG_VM enabled. It pass the KSM testing in LTP and kernel selftest. Thanks for Matthew Wilcox and David Hildenbrand's suggestions and comments! This patch (of 10): The ksm only contains single pages, so we could add a new func ksm_get_folio for get_ksm_page to use folio instead of pages to save a couple of compound_head calls. After all caller replaced, get_ksm_page will be removed.

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 reStructuredText 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.
