Subject: xfs: set XFS_FEAT_NLINK correctly
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ea0ce7c13610bcfb8cf77cf93558c82bba820b72;p=linux.git

xfs: set XFS_FEAT_NLINK correctly

[ 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().
