If a call to kobject_init_and_add() fails we must call kobject_put()
otherwise we leak memory.
Function gfs2_sys_fs_add always calls kobject_init_and_add() which

It is safe to leave object destruction up to the kobject release

There's currently a problem with toggling arp_validate on and off with an
active-backup bond. At the moment, you can start up a bond, like so:
modprobe bonding mode=1 arp_interval=100 arp_validate=0 arp_ip_targets=192.168.1.1
ip link set bond0 down
echo "ens4f0" > /sys/class/net/bond0/bonding/slaves
echo "ens4f1" > /sys/class/net/bond0/bonding/slaves
ip link set bond0 up
ip addr add 192.168.1.2/24 dev bond0
Pings to 192.168.1.1 work just fine. Now turn on arp_validate:
echo 1 > /sys/class/net/bond0/bonding/arp_validate
Pings to 192.168.1.1 continue to work just fine. Now when you go to turn
arp_validate off again, the link falls flat on it's face:
echo 0 > /sys/class/net/bond0/bonding/arp_validate
dmesg
...
[133191.911987] bond0: Setting arp_validate to none (0)
[133194.257793] bond0: bond_should_notify_peers: slave ens4f0
[133194.258031] bond0: link status definitely down for interface ens4f0, disabling it
[133194.259000] bond0: making interface ens4f1 the new active one
[133197.330130] bond0: link status definitely down for interface ens4f1, disabling it
[133197.331191] bond0: now running without any active interface!
The problem lies in bond_options.c, where passing in arp_validate=0
results in bond->recv_probe getting set to NULL. This flies directly in
the face of commit 3fe68df97c, which says we need to set recv_probe =
bond_arp_recv, even if we're not using arp_validate. Said commit fixed
this in bond_option_arp_interval_set, but missed that we can get to that
same state in bond_option_arp_validate_set as well.
One solution would be to universally set recv_probe = bond_arp_recv here
as well, but I don't think bond_option_arp_validate_set has any business
touching recv_probe at all, and that should be left to the arp_interval
code, so we can just make things much tidier here.

Including:

- AUX domain support in the IOMMU-API and the Intel VT-d driver.
This adds support for multiple DMA address spaces per

SR-IOV.
- The Rest are smaller cleanups and fixes, two of which needed

Merge tag 'iommu-updates-v5.2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
- ATS support for ARM-SMMU-v3.
- AUX domain support in the IOMMU-API and the Intel VT-d driver. This
adds support for multiple DMA address spaces per (PCI-)device. The
use-case is to multiplex devices between host and KVM guests in a
more flexible way than supported by SR-IOV.
- the rest are smaller cleanups and fixes, two of which needed to be
reverted after testing in linux-next.

pull-request: bpf 2019-05-13
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix out of bounds backwards jumps due to a bug in dead code
removal, from Daniel.
2) Fix libbpf users by detecting unsupported BTF kernel features
and sanitize them before load, from Andrii.
3) Fix undefined behavior in narrow load handling of context
fields, from Krzesimir.
4) Various BPF uapi header doc/man page fixes, from Quentin.
5) Misc .gitignore fixups to exclude built files, from Kelsey.

Commit 31fd85816d ("bpf: permits narrower load from bpf program
context fields") made the verifier add AND instructions to clear the
unwanted bits with a mask when doing a narrow load. The mask is
computed with
(1 << size * 8) - 1
where "size" is the size of the narrow load. When doing a 4 byte load
of a an 8 byte field the verifier shifts the literal 1 by 32 places to
the left. This results in an overflow of a signed integer, which is an
undefined behavior. Typically, the computed mask was zero, so the
result of the narrow load ended up being zero too.
Cast the literal to long long to avoid overflows. Note that narrow
load of the 4 byte fields does not have the undefined behavior,
because the load size can only be either 1 or 2 bytes, so shifting 1
by 8 or 16 places will not overflow it. And reading 4 bytes would not
be a narrow load of a 4 bytes field.

Depending on used versions of libbpf, Clang, and kernel, it's possible to
have valid BPF object files with valid BTF information, that still won't
load successfully due to Clang emitting newer BTF features (e.g.,
BTF_KIND_FUNC, .BTF.ext's line_info/func_info, BTF_KIND_DATASEC, etc), that
are not yet supported by older kernel.
This patch adds detection of BTF features and sanitizes BPF object's BTF
by substituting various supported BTF kinds, which have compatible layout:
- BTF_KIND_FUNC -> BTF_KIND_TYPEDEF
- BTF_KIND_FUNC_PROTO -> BTF_KIND_ENUM
- BTF_KIND_VAR -> BTF_KIND_INT
- BTF_KIND_DATASEC -> BTF_KIND_STRUCT
Replacement is done in such a way as to preserve as much information as
possible (names, sizes, etc) where possible without violating kernel's
validation rules.
v2->v3:
- remove duplicate #defines from libbpf_util.h
v1->v2:
- add internal libbpf_internal.h w/ common stuff
- switch SK storage BTF to use new libbpf__probe_raw_btf()

====================
Another round of fixes for the doc in the BPF UAPI header, which can be
turned into a manual page. First patch is the most important, as it fixes
parsing for the bpf_strtoul() helper doc. Following patches are formatting
fixes (nitpicks, mostly). The last one updates the copy of the header,
located under tools/.
