What's even more odd is that the very previous line also uses ipaddrs, yet it does not trigger the warning.
In any case I believe it's a false positive, since the only way it could remain unitialized is if
libcfs_ipif_enumerate returned negative value (stored in nif in this function) and we check for it being more than zero
before getting to that part of code.
I'll submit a patch assigning ipaddrs to NULL as a workaround shortly.
Bye,
Oleg
