[PATCH 14/18] fs/ntfs3: Merge synonym COMPRESSION_UNIT and NTFS_LZNT_CUNIT

From: Konstantin Komarov
Date: Fri Jun 07 2024 - 08:18:44 EST


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.
