Subject: [PATCH 1/3] arch/Kconfig: Split PAGE_SIZE_LESS_THAN_256KB from PAGE_SIZE_LESS_THAN_64KB
Date: Mon, 29 Nov 2021 16:01:39 -0700 [thread overview]
Message-ID: <20211129230141.228085-2-nathan@kernel.org> (raw)
In-Reply-To: <20211129230141.228085-1-nathan@kernel.org>
btrfs requires a page size smaller than 256kB. To use that dependency in
other places, introduce CONFIG_PAGE_SIZE_LESS_THAN_256KB and reuse that
dependency in CONFIG_PAGE_SIZE_LESS_THAN_64KB.
