--JViz224v3YRbOSfM Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi all, It seems the default timestamp precision sysctl (vfs.timestamp_precision) is currently set to 0 by default, meaning we don't do any sub-second timestamps on files. Looking at the code, it seems that vfs.timestamp_precision=3D1 will let it use a cached value with 1 / HZ precision and it looks like it should have little overhead. Would anyone object if I were to change the default from 0 to 1? --=20 Ed Schouten <ed@80386.nl> WWW: http://80386.nl/ --JViz224v3YRbOSfM Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (FreeBSD) iQIcBAEBAgAGBQJPNSHPAAoJEG5e2P40kaK7jmQP+wXjcKunhXA/kuBJH53bUzXt rAr3mojSf2DxLd+ldJxmbuylszwG6b06IZVK8I7nbQQVZMoZa1x1YhRmnN86Fv9j Sy0a1O+7LF1ddFClIKVasO1ULW+BbaRNTIEjhGqTiXJ4W96HluGSCx2jnaZHCvCE 86vb0QPzBq7Nbfb+n+uMT0JbIy9+z21zoH7TbWTFB9kQoTlX5l0VB7uFOSknvHKQ 3WTwZij90DaF7PfSX/YaksI/FTsG92Pqgm4VRKtzHgzJmRn8+kSvoCu7pEtXM08R +m1jbMQSrPNSueiqMIVNdxridfUiKyjae+gAg+7r3s7RjaiJ/8vSxfJLul3wk5WK FzZhp0CoG+Tetp0310qHummN2MyFtqEXaF5hUSTeK1YWp6m/8CQz3RGHkS7nQD1Q 3VUlcTU66MMRt63MPvswKoIutmzPSufW4zB93F1z9pv5jVdjXfNnieU3rRAGOx7v FfOARp6Vzs5eIUcqFKvWO5x4ob2Jellw/QOSWT2bcF9kKoX3WJdJMo9eCTPP26Py YF77pSCX1WaPTZuecaXFeRpk35QKnqr4VZgBhJ59JqSGooOlSwyUkuID3xsAju+u J/Tgi23KybqHdpZrGkmkmDNtrR96ygBjZKRR93P5UceIIsJ8dPy5Qwk8W9X4KJnJ fLmJz7yK8RTWGrfwqceJ =RWu+ -----END PGP SIGNATURE----- --JViz224v3YRbOSfM--
