Its filename is xor-split-xorh.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/xor-split-xorh.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: xor: split xor.h Date: Fri, 27 Mar 2026 07:16:40 +0100 Keep xor.h for the public API, and split the struct xor_block_template definition that is only needed by the xor.ko core and architecture-specific optimizations into a separate xor_impl.h header.
