In one of my previous commits I've introduced code that creates
|
|
|
d76c62 |
all devices for given (possible) multipath target. But I've made
|
|
|
d76c62 |
a mistake there - the code accesses 'next->path' without checking
|
|
|
d76c62 |
if the disk source is local. Note that the 'next->path' is
|
|
|
d76c62 |
NULL/doesn't make sense for VIR_STORAGE_TYPE_NVME.
