RH-Commit: [4/5] 48ead2f35d8558fda48a2098240c0203f4c547b0 (hreitz/qemu-kvm-c-9-s)
|
|
|
|
After clearing our state (memset()-ing it to 0), we should
|
|
re-initialize objects that need it. Specifically, that applies to
|
|
s->lock, which is originally initialized in qcow2_open().
|
|
|
|
Given qemu_co_mutex_init() is just a memset() to 0, this is functionally
|
|
a no-op, but still seems like the right thing to do.
