In linux kernel since version 4.14.327 (release Date: 2023-10-10)
If you say Y here, support for write intent bitmaps in files on an
external file system is enabled. This is an alternative to the internal
bitmaps near the MD superblock, and very problematic code that abuses
various kernel APIs and can only work with files on a file system not
actually sitting on the MD device.
