Some incompat features are only used in newer versions like ext3 and ext4, while others are added to ext2 too.

As I don't know what the f*** do META_BG and FLEX_BG do, I can't tell you whether they truly work or it's just a matter of luck: it's Bean who can tell us whether or not he implemented support for them - I only added the "extents" flag to the supported list on my patch, but including more is a matter of seconds. --=-lhZg3Qz9Kq5vcdvii84F Content-Type: application/pgp-signature; name=signature.asc Content-Description: Esta parte del mensaje =?ISO-8859-1?Q?est=E1?= firmada digitalmente -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iQIVAwUASH4j8aSl+Fbdeo72AQK9lQ/+Lj+Wfg/WZLF2n860iLm33IuUe8Alp8y4 aGsalmrBB3R6YHaWdMGT2rw+KLfYu1j17EWH3C7/py1rgcf+mlpx+JFsEPSFFztf Bw/i7lvLhvTXpgz7KlqJWEXPo4G+45UYJoVx3VLAV2G/SXg1850tzTiDzpXTyc9E 2+NxycD2vA0L8c2s6JyOcPjLuietvy69kpCLysvPpZdbceTX666hn6dKgTA1Z40e 09Enera8cz8RgtwbP/d0QNJz6biEaRVu+/gFQCzR6d6CfSz3lWTOhUh6miF1Gq3K 8fwET0tdzNm4VAPhtBZvJXsJT2my+xo4jXB2CRNUPjdOzi83/Rk7mKySgLF41Qx1 ZT/5UG/io1tqi1z1j8syoVt9ktv+pcAuxvGTcm6JsYRGQjfrs3Zg1Juhn3wRiXmJ yhEeHqGujI+whuJEgBug8lC4NUfQsllTTKsI1IShfeNTqK5esiDFR8RxexK2nztR o4fVaNqJMbFnbYU+vPdj1Hc0ZGNM4/ckboMKvhZyAFuo4rpPiXp1iV5eJIJbFMtf UzqZ+BgB7CCqBNYcYhsy7pxWltbY76HjKrlwcFqBBXxdp4rDIUY6ytJHfm6LQNsZ BpPf3n5q6zN9g/8Cevu5x5NHKa9MarNtsP5chw2HQ9P1VIHiDW/px6n0yC0bM1WY pw8Hms0dINE= =reyR -----END PGP SIGNATURE----- --=-lhZg3Qz9Kq5vcdvii84F--
