6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Konstantin Komarov <almaz.alexandrovich@xxxxxxxxxxxxxxxxxxxx>
[ Upstream commit 487f8d482a7e51a640b8f955a398f906a4f83951 ]
COMPRESSION_UNIT and NTFS_LZNT_CUNIT mean the same thing
(1u<<NTFS_LZNT_CUNIT) determines the size for compression (in clusters).
COMPRESS_MAX_CLUSTER is not used in the code.
