Hardcoded subvolids break noholes test runs, so change the test to use
_btrfs_get_subvolid instead of assuming 256, 257, etc...

How exactly does no-holes affect the assigned IDs to subvolumes?
It's a default feature for quite a while and the test passes with it
and without it (-O ^no-holes).

Aren't you confusing this with enabling or disabling features that add
some tree?
Like disabling the free space tree (which is a default for quite a
while now), for example.

For me it fails with -O ^free-space-tree, and it fails even with this
patch applied:

I see variables like subvid below being declared as global in one
function and then used in other functions.
Maybe there's something wrong with that... it would be cleaner to make
the variable local and pass the subvolume id as an argument to other
functions.

Thanks.

Make the variable local please.

Yes I am. Josef reported this to me and I misread the name of his
configuration that was failing. For completeness it was one that doesn't
use free space tree, like you say.

And didn't reproduce it, since he proposed the fix, which seemed
"straightforward" enough to me.

I tried to test that they get populated correctly (confused why it works
sometimes...)

But clearly it's broken in general and I'll do something more robust. I
think the basic problem is I call prepare() in each test function, so I
wanted prepare to set the global state, without making each test lookup
the subvolid. But it's not the end of the world to have the tests get it
one way or the other.

Thanks for catching the mistake.
