You didn't insert g_reset_bio calls after all g_alloc_bio calls, for example in vdev_geom_io_start. Do you intend to follow up this change with a g_reset_bio everywhere that g_alloc_bio is called, or did you mean that g_reset_bio is optional after all bios returned by g_{new,alloc}_bio? _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
