Subject: Re: net.git: Call-trace after "Merge branch 'netlink_multicast'"

Just a small thing, if you look at this...

With gcc-4.9.2 I see this warning in my logs...

net/netlink/genetlink.c: In function 'genl_bind':
net/netlink/genetlink.c:1018:2: warning: 'err' may be used
uninitialized in this function [-Wmaybe-uninitialized]

- Sedat -

P.S.: Some gcc-4.9 outputs
