Just to be pedantic, osyncisdsync "exists," but is deprecated and does nothing to change defaults: } else if (!strcmp(this_char, "osyncisdsync")) { /* no-op, this is now the default */ cmn_err(CE_WARN, "XFS: osyncisdsync is now the default, option is deprecated."); } huh, didn't realize that osyncisosync does nothing but set a flag that is never tested other than to show mount options: File Function Line 0 xfs_mount.h 285 #define XFS_MOUNT_OSYNCISOSYNC (1ULL << 13) 1 linux-2.6/xfs_super.c xfs_parseargs 292 mp->m_flags |= XFS_MOUNT_OSYNCISOSYNC; 2 linux-2.6/xfs_super.c xfs_showargs 542 { XFS_MOUNT_OSYNCISOSYNC, "," MNTOPT_OSYNCISOSYNC }, Time to deprecate/remove that one too I guess? -Eric > Cheers, > > Dave. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
