With the recent change in metadata handling, we can handle metadata in the following cases: - nodesize < PAGE_SIZE and sectorsize < PAGE_SIZE Go subpage routine for both metadata and data. - nodesize < PAGE_SIZE and sectorsize >= PAGE_SIZE Invalid case for now. As we require nodesize >= sectorsize. - nodesize >= PAGE_SIZE and sectorsize < PAGE_SIZE Go subpage routine for data, but regular page routine for metadata. - nodesize >= PAGE_SIZE and sectorsize >= PAGE_SIZE Go regular page routine for both metadata and data. Now we can handle any sectorsize < PAGE_SIZE, plus the existing sectorsize == PAGE_SIZE support. But here we introduce an artificial limit, any PAGE_SIZE > 4K case, we will only support 4K and PAGE_SIZE as sector size. The idea here is to reduce the test combinations, and push 4K as the default standard in the future.

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.
