Commitb05fbcc36b("btrfs: disable build on platforms having page size 256K") disabled btrfs for configurations that used a 256kB page size. However, it did not fully solve the problem because CONFIG_TEST_KMOD selects CONFIG_BTRFS, which does not account for the dependency. This results in a Kconfig warning and the failed BUILD_BUG_ON error returning. WARNING: unmet direct dependencies detected for BTRFS_FS Depends on [n]: BLOCK [=y] && !PPC_256K_PAGES && !PAGE_SIZE_256KB [=y] Selected by [m]: - TEST_KMOD [=m] && RUNTIME_TESTING_MENU [=y] && m && MODULES [=y] && NETDEVICES [=y] && NET_CORE [=y] && INET [=y] && BLOCK [=y] To resolve this, add CONFIG_PAGE_SIZE_LESS_THAN_256KB as a dependency of CONFIG_TEST_KMOD so there is no more invalid configuration or build errors.

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.
