1) :
for example:
BDRVQcowState *s = bs->opaque;
s->snapshots
s->nb_snapshots
1:use the command: qemu-img snapshot ./test.qcow2 -c aa
the memory of the s->snapshot don't free,
if the s->nb_snapshots is large, Does it have some problems.
2: use the command: qemu-system-x86_64 ./test.qcow2 -snapshot
when the program ends, Does it need to free the s->snapshots ?
2):
in the function of
qcow2_update_snapshot_refcount
it has some " goto fail ";
if the function runs some times, then something makes it goto fail,
I am not sure whether it will make the refcount incorrect.
