Its filename is arm64-xor-fix-conflicting-attributes-for-xor_block_template.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/arm64-xor-fix-conflicting-attributes-for-xor_block_template.patch This patch will later appear in the mm-nonmm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via various branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there most days ------------------------------------------------------ From: Christoph Hellwig Subject: arm64/xor: fix conflicting attributes for xor_block_template Date: Fri, 27 Mar 2026 07:16:35 +0100 Commit 2c54b423cf85 ("arm64/xor: use EOR3 instructions when available") changes the definition to __ro_after_init instead of const, but failed to update the external declaration in xor.h. This was not found because xor-neon.c doesn't include , and can't easily do that due to current architecture of the XOR code.
