This is more or less the same kind of fixes that we made in the rest of qcow2
last year: Return the right error codes and make the order of operations safe
so that a crash can lead to no more than cluster leaks.
Although all of these are bug fixes, I'm not so sure about taking them into
1.0. Maybe we can take some of the easier ones and leave others out, or just
move the whole series to 1.1. Feedback on this would appreciated.
Kevin Wolf (8):
qcow2: Return real error code in qcow2_read_snapshots
qcow2: Return real error code in qcow2_write_snapshots
qcow2: Cleanups and memleak fix in qcow2_snapshot_create
qcow2: Rework qcow2_snapshot_create error handling
qcow2: Return real error in qcow2_snapshot_goto
qcow2: Fix order of refcount updates in qcow2_snapshot_goto
qcow2: Fix order in qcow2_snapshot_delete
qcow2: Fix error path in qcow2_snapshot_load_tmp
