Update of /cvsroot/bsdext2fs/src In directory sc8-pr-cvs3.sourceforge.net:/tmp/cvs-serv30872 Modified Files: ext2fs_lookup.c ext2fs_vfsops.c ext2fs_vnops.c Log Message: The next round of syncing w/ FreeBSD: o Pick up GEOM accidently forgotten in prev. commits to leave from devfs. o Init (also forgotten *blush*) cp geom consumer so we do not call instruction on NULL addr (I don't know how that can happen). o There was recent KPI changes in CURRENT. Now it build in both 7+ and 8. o I do not understand why we loop in unmount op if MNT_LAZY is set so I simply dropped that code. o Do not call ufs ops where they don't belong to.
