I'll just double check that you got all usages of xfs_alloc_arg_t:
xfs_inobt_alloc_block... fixed in f5eb8e7c by HCH
xfs_ialloc_ag_alloc... fixed below
xfs_bmbt_alloc_block... also fixed in f5eb8e7c
xfs_bmap_local_to_extents... fixed below
xfs_bmap_extents_to_btree... fixed below
xfs_bmap_btalloc... fixed below
xfs_free_extent... fixed in 0e1edbd9 by Nathan Scott
xfs_alloc_fix_freelist... fixed below
Looks good!
