Since we have btrfs_meta_is_subpage(), we should make btrfs_is_subpage() to be data inode specific. This change involves: - Simplify btrfs_is_subpage() Now we only need to do a very simple sectorsize check against PAGE_SIZE. And since the function is pretty simple now, just make it an inline function. - Add an extra ASSERT() to make sure btrfs_is_subpage() is only called on data inode mapping - Migrate btree_csum_one_bio() to use btrfs_meta_folio_*() helpers - Migrate alloc_extent_buffer() to use btrfs_meta_folio_*() helpers - Migrate end_bbio_meta_write() to use btrfs_meta_folio_*() helpers Or we will trigger the ASSERT() due to calling btrfs_folio_*() on metadata folios.

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.
