Developers,
While trying to upgrade from backports v3.11.8 to v3.13.2 I ran into
this warning:
WARNING: "atomic64_set"
[/home/dschultze/dump/ltib-trunk/rpm/BUILD/backports-3.13.2-1/net/mac80211/mac80211.ko]
undefined!
I have verified that the kernel (v2.6.31, arm) does indeed have a
definition for this function but for some reason mac80211.ko cannot
see it. I was able to use the following patch as a hack to provide an
implementation for mac80211.ko.
diff -Nur backports-3.13.2-1-orig/net/mac80211/key.c

{
I know that using this hack isn't the best way to go but I'm not sure
how to resolve the issue: why can't backports use the function and
exported symbol from the kernel?
Thank you,
Daniel Schultze
