[PATCH 5.15 27/83] xfs: set XFS_FEAT_NLINK correctly

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

 



From: Dave Chinner <dchinner@xxxxxxxxxx>

[ Upstream commit dd0d2f9755191690541b09e6385d0f8cd8bc9d8f ]

While xfs_has_nlink() is not used in kernel, it is used in userspace
(e.g. by xfs_db) so we need to set the XFS_FEAT_NLINK flag correctly
in xfs_sb_version_to_features().
