Subject: [patch 52/55] lib/Kconfig.debug: make TEST_KMOD depend on PAGE_SIZE_LESS_THAN_256KB
Date: Wed, 19 Jan 2022 18:10:28 -0800	[thread overview]
Message-ID: <20220120021028.4n6F60o75%akpm@linux-foundation.org> (raw)
In-Reply-To: <20220119180714.9e187ce100e4510de3cd9f7d@linux-foundation.org>

From: Nathan Chancellor <nathan@kernel.org>
Subject: lib/Kconfig.debug: make TEST_KMOD depend on PAGE_SIZE_LESS_THAN_256KB

Commit b05fbcc36be1 ("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.
