We should skip the test with such old versions (it's usually what we do everywhere) or make it fallback to the sleep. We have "_require_btrfs <command>" to check if btrfs-progs supports a specific command, so we could extend it to check for a subcommand too as an optional argument so we could call "_require_btrfs subvolume sync" in the test. > > _scratch_unmount > > diff --git a/tests/btrfs/group b/tests/btrfs/group > index ef6c260..9403daa 100644 > --- a/tests/btrfs/group > +++ b/tests/btrfs/group > @@ -104,7 +104,7 @@ > 101 auto quick replace > 102 auto quick metadata enospc > 103 auto quick clone compress > -104 auto qgroup > +104 auto quick qgroup > 105 auto quick send > 106 auto quick clone compress > 107 auto quick prealloc > -- > 2.1.4 > > -- > To unsubscribe from this list: send the line "unsubscribe fstests" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- Filipe David Manana, "Reasonable men adapt themselves to the world.
