I would prefer to have an exported kernel function that fills xswdev by index, used both by vm_swap_info and linprocfs. For the device name, you would use sw_vp->v_rdev->si_name, see, for instance, the following fragment in the swapoff_all(): if (vn_isdisk(sp->sw_vp, NULL)) devname =3D sp->sw_vp->v_rdev->si_name; else devname =3D "[file]"; This could be another function that returns swap information by index. --DVQ8A37yL26ZH/UD Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (FreeBSD) iEYEARECAAYFAk4x8kUACgkQC3+MBN1Mb4hLSQCfaZs58R1WxyV3tmZ59T0N6Z+k DeIAn22z6GLMtJGi3qP6zXo3Op4iL1Wz =Kq/Y -----END PGP SIGNATURE----- --DVQ8A37yL26ZH/UD--
