[to-be-updated] xor-split-xorh.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: xor: split xor.h
has been removed from the -mm tree.  Its filename was
     xor-split-xorh.patch

This patch was dropped because an updated version will be issued

------------------------------------------------------
From: Christoph Hellwig <hch@lst.de>
Subject: xor: split xor.h
Date: Tue, 24 Mar 2026 07:21:43 +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.
