Linux kernel source tree
78fefd04c1
Patch series "mm: improve clear and copy user folio", v2. Some folio conversions. An improvement is to move address alignment into the caller as it is only needed if we don't know which address will be accessed when clearing/copying user folios. This patch (of 4): Replace clear_huge_page() with folio_zero_user(), and take a folio instead of a page. Directly get number of pages by folio_nr_pages() to remove pages_per_huge_page argument, furthermore, move the address alignment from folio_zero_user() to the callers since the alignment is only needed when we don't know which address will be accessed.

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.
