xfs_acl_vget is used for getting the posix acl EA and not for the XFS acl.

The func is static to xfs_acl.c .

How about using:
_ACL_GET_ACCESS(pv,pa) for the XFS access ACL
(which ends up calling xfs_acl_vtoacl()).
This function will get the xfs_acl given the vnode.
any reason why we have
extern int xfs_acl_get(struct vnode *, xfs_acl_t *, xfs_acl_t *);
extern int xfs_acl_set(struct vnode *, xfs_acl_t *, xfs_acl_t *);
in xfs_acl.h ?
