> Hello,
>  In patch 1/4 a race condition while changing the bonding mode through
>  sysfs is fixed. Since no synchronization method is used it can race
>  with different functions resulting in different impacts. RTNL is used
>  to sync with the most important and dangerous events.
>  Patch 2/4 is trivial and improves the debugging output by changing %x
>  format to %pI4 for IPv4 addresses in a few pr_debug() calls.
>  Patch 3/4 fixes an inconsistent arp_targets state where we have 0 entry
>  between (or in the beginning) the valid entries that were obtained which
>  is hard to diagnose otherwise.
>  Patch 4/4 fixes multiple instances of a race condition which is because of
>  calls to bond_3ad_get_active_agg_info without any locking, and since it 
>  traverses the slave list this can easily result in NULL ptr dereference or
>  use of freed memory.
> 
>  v2 is to address a minor style fix, to make the wrapper
>  global and move it to bond_3ad.c, and also to fix the naming of the
>  functions, all in patch 4/4.

Series applied, thanks.
