Its filename was xor-add-a-better-public-api-2.patch This patch was dropped because it was folded into xor-add-a-better-public-api.patch ------------------------------------------------------ From: Christoph Hellwig Subject: xor: add a better public API Date: Fri, 27 Mar 2026 07:16:55 +0100 xor_blocks is very annoying to use, because it is limited to 4 + 1 sources / destinations, has an odd argument order and is completely undocumented. Lift the code that loops around it from btrfs and async_tx/async_xor into common code under the name xor_gen and properly document it.
