Fix iscsiuio segfault when shutting down.
|
||
|
|
|
||
|
|
If iscsiuio is stopped when first starting up, it can easily
|
||
|
|
hit a window where pthread_cancel() is called before pthread_create()
|
||
|
|
finishesx The problem was found by kiyo@jp.fujitsu.com, who also
|
||
|
|
proposed the fix.
