Bug Description

SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The 4.4.101 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.

       git://git.kernel.org/

    TEST CASE: TBD

       The following patches from the 4.4.101 stable release shall be applied:
* tcp: do not mangle skb->cb[] in tcp_make_synack()
* netfilter/ipvs: clear ipvs_property flag when SKB net namespace changed
* bonding: discard lowest hash bit for 802.3ad layer3+4
* vlan: fix a use-after-free in vlan_device_event()
* af_netlink: ensure that NLMSG_DONE never fails in dumps
* sctp: do not peel off an assoc from one netns to another one
* fealnx: Fix building error on MIPS
* net/sctp: Always set scope_id in sctp_inet6_skb_msgname
* ima: do not update security.ima if appraisal status is not INTEGRITY_PASS
* serial: omap: Fix EFR write on RTS deassertion
* arm64: fix dump_instr when PAN and UAO are in use
* nvme: Fix memory order on async queue deletion
* ocfs2: should wait dio before inode lock in ocfs2_setattr()
* ipmi: fix unsigned long underflow
* mm/page_alloc.c: broken deferred calculation
* coda: fix 'kernel memory exposure attempt' in fsync
* mm: check the return value of lookup_page_ext for all call sites
* mm/page_ext.c: check if page_ext is not prepared
* mm/pagewalk.c: report holes in hugetlb ranges
* Linux 4.4.101

The following patch was NOT applied:

 * nvme: Fix memory order on async queue deletion

The reason is that this patch fixes a race condition in function async_completion() in drivers/nvme/host/pci.c . However, this function had been removed entirely in commit c33e9323c87556f335378113837cab4aab7d8a85 as part of http://bugs.launchpad.net/bugs/1531539

Therefore I believe that patch is no longer necessary for Xenial and so I skipped it.

In regards to comment #1 - additional testing, especially around the nvme area, would be nice.

On comment #1: The patch that was skipped mentions that
 db3cbfff5bcc0 "NVMe: IO queue deletion re-write"
fixes the issue in a different manner but would not qualify as a stable candidate due to its size. But as you found we did a rather large backport for bug #1531539 which does include the mentioned patch (already applied pre-release of Xenial in Ubuntu-4.4.0-9.24). So it is indeed not needed in Xenial.
