When running 'lxc' on the latest -stable kernel, 3.14.28, I'm seeing
these errors:
Jan 14 17:47:16 lxc2 kernel: [ 10.704890] WARNING: CPU: 0 PID: 3209 at
fs/sys
fs/dir.c:52 sysfs_warn_dup+0x8c/0xb0()
Jan 14 17:47:16 lxc2 kernel: [ 10.704892] sysfs: cannot create
duplicate filename '/devices/virtual/net/eth0.104/upper_eth0'

lxc-autostart Not tainted 3.14.28-xsserver #1
I did not see these errors in 3.12. This was fixed in 3.17 by:
net: prevent of emerging cross-namespace symlinks
https://github.com/torvalds/linux/commit/4c75431ac3520631f1d9e74aa88407e6374dbbc4
net: fix creation adjacent device symlinks
https://github.com/torvalds/linux/commit/7ce64c79c4decdeb1afe0bf2f6ef834b382871d1
These patches apply cleanly to 3.14.28.
If you agree that this should go into 3.14-stable, please ack.
Thanks,
Mike.
