Subject: [PATCH] arm64/mm: Drop redundant extern declaration for rodata_full
Date: Wed, 15 Oct 2025 03:36:09 +0100 [thread overview]
Message-ID: <20251015023609.427911-1-anshuman.khandual@arm.com> (raw)
Drop the redundant extern declaration 'rodata_full' which can be included
via the header <asm/setup.h> after moving exiting declaration outside the
function arch_parse_debug_rodata(). While here also drop 'rodata_enabled'
which is anyways available via the generic header <linux/init.h>.
