Subject: [PATCH 0/3] init/Kconfig: generalize config COMMAND_LINE_SIZE
Date: Thu, 6 Aug 2026 06:14:13 +0000 [thread overview]
Message-ID: <20260806061429.474992-1-wfelipe@google.com> (raw)
[Note: Resending the full series to ensure all patches are delivered with a
unified recipient and CC list across all mailing lists.]
This patch series promotes COMMAND_LINE_SIZE from arch/s390/Kconfig to
init/Kconfig to be generally available to other architectures.
In some use cases, such as netboot kernels, rootfs configurations, larger
initramfs setups, require larger sizes. While for embedded workloads, it
can be reduced to save memory.
Since COMMAND_LINE_SIZE can be larger, it also makes sense to allow
INIT_ENV_ARG_LIMIT to be configured.
Wilson Felipe Pereira (3):
init/Kconfig: generalize config COMMAND_LINE_SIZE to all architectures
arch: use CONFIG_COMMAND_LINE_SIZE across all architectures
init/Kconfig: make config INIT_ENV_ARG_LIMIT user-configurable
