[PATCH 5.15 150/484] fs/ntfs3: Merge synonym COMPRESSION_UNIT and NTFS_LZNT_CUNIT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.15-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.
