Commit e2b8247a322 introduced an error path in qemu_rbd_open() after
|
|
|
26ba25 |
calling rbd_open(), but neglected to close the image again in this error
|
|
|
26ba25 |
path. The error path should contain everything that the regular close
|
|
|
26ba25 |
function qemu_rbd_close() contains.
|
|
|
26ba25 |
|
|
|
26ba25 |
This adds the missing rbd_close() call.
