This is a conversion of the remaining xfs_sb_version_has..(sbp) checks to use xfs_has_..(mp) feature checks. This was largely done with a vim replacement macro that did: :0,$s/xfs_sb_version_has\(.*\)&\(.*\)->m_sb/xfs_has_\1\2/g<CR> A couple of other variants were also used, and the rest touched up by hand. $ size -t fs/xfs/built-in.a text data bss dec hex filename before 1127533 311352 484 1439369 15f689 (TOTALS) after 1125360 311352 484 1437196 15ee0c (TOTALS) Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.
