Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next
Steffen Klassert says: ==================== pull request (net-next): ipsec-next 2014-07-30 This is the last pull request for ipsec-next before I'll be off for two weeks starting on friday. David, can you please take urgent ipsec patches directly into net/net-next during this time? 1) Error handling simplifications for vti and vti6. From Mathias Krause. 2) Remove a duplicate semicolon after a return statement. From Christoph Paasch. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
