Request for review for 4.4-st73, 4.4-cip108

[Ulrich Hecht]

Hi!

Here are the manual backports for the upcoming 4.4 kernel release. As always they can be found in https://git.kernel.org/pub/scm/linux/kernel/git/cip/linux-cip.git/log/?h=linux-4.4.y-st-rc

dd2af1ff15baa macvlan: fix possible UAF in macvlan_forward_source()
6e7f9685b9d35 wifi: wlcore: ensure skb headroom before skb_push
1b847006e7141 sctp: move SCTP_CMD_ASSOC_SHKEY right after SCTP_CMD_PEER_INIT
bf3c650dfddf3 btrfs: fix deadlock in wait_current_trans() due to ignored transaction type
9dbc25309be1c net/sched: sch_qfq: do not free existing class in qfq_change_class()

Plus one fix for my convenience:

e0e89cfcf08df arm64: replace Sun/Solaris style flag on section directive

Thanks for having a look!

Pointer "mainline equivalent of this is XXX" would be nice here.

Thanks and best regards,

Normally yes, but in this case there is none. The offending line disappeared organically during post-4.4 mainline development before it could become an issue there.
