>From Documentation/admin-guide/kernel-parameters.txt, we know that: rodata= [KNL,EARLY] on Mark read-only kernel memory as read-only (default). off Leave read-only kernel memory writable for debugging. full Mark read-only kernel memory and aliases as read-only [arm64] So the "rodata=on" is the default. But the current code does not follow the document, it makes "rodata=full" as the default. This patch set follows Anshuman Khandual's suggetions. It makes the "rodata=on" as the default, and removes the CONFIG_RODATA_FULL_DEFAULT_ENABLED. v7: Change the code by following Will's suggestions. v6: Fix a small issue pointed by Randy Dunlap. https://lists.infradead.org/pipermail/linux-arm-kernel/2025-July/1041488.html v5: Rebase this patch set with linux-next20250627 https://lists.infradead.org/pipermail/linux-arm-kernel/2025-June/1040297.html v4: Follows Anshuman Khandual/Ard Biesheuvel's suggetions: - Change commit message format. - Change the titile name. - others https://lists.infradead.org/pipermail/linux-arm-kernel/2024-December/985629.html v3: Follows Anshuman Khandual's suggetions: - Merge patch 1 and patch 3 into one patch. - Remove patch 4 - update comments and document. https://lists.infradead.org/pipermail/linux-arm-kernel/2024-December/984344.html v2: Follows Will's suggetions.
