Subject: Snapshot cannot be deleted

Hi,

Due to the known (and fixed) bug in kernel 3.17.0 one of my btrfs
volume suffers from unreadable and - even worse - uneraseable
snapshots. Whenever such a snapshot is accessed there is "parent
transid verify failed" in dmesg.
Is there any way to delete these snapshots?

Thanks,
Andreas
