Linux kernel source tree
5fbaae4b85
This involves: - Migrate scrub_stripe::pages[] to folios[] - Use btrfs_alloc_folio_array() and folio_put() to alloc above array. - Migrate scrub_stripe_get_kaddr() and scrub_stripe_get_paddr() to use folio interfaces - Migrate raid56_parity_cache_data_pages() to raid56_parity_cache_data_folios() Since scrub is the only caller still using pages. This helper will copy the folio array contents into rbio::stripe_pages, with sector uptodate flags updated. And a new ASSERT() to make sure bs > ps cases will not hit this path. Since most scrub code is based on kaddr/paddr, the migration itself is pretty straightforward. And since we're here, also move the loop to set the stripe_sectors[].uptodate out of the copy loop. As we always mark all the sectors as uptodate for the data stripe, it's easier to do in one go, other than doing it inside the copy loop.

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.
