Hi boris,
I take a quick look at the code branch and I think it is a Bug indeed.
THe code just forgot to set the proper return value before leave out.
To test whether a dir is a subvolume, what about
# btrfs sub list | grep <dirname>
as 'btrfs sub list will list all subvolumes under <mntpoint>.
The dirname should be relative path under <mntpoint> is as I could
remember.
Thanks,
Gui
