When f_setown is called a pid and a pid type are stored. Replace the use
of PIDTYPE_PID with PIDTYPE_TGID as PIDTYPE_TGID goes to the entire thread
group. Replace the use of PIDTYPE_MAX with PIDTYPE_PID as PIDTYPE_PID now
is only for a thread.
Update the users of __f_setown to use PIDTYPE_TGID instead of
PIDTYPE_PID.
For now the code continues to capture task_pid (when task_tgid would
really be appropriate), and iterate on PIDTYPE_PID (even when type ==
PIDTYPE_TGID) out of an abundance of caution to preserve existing
behavior.
Oleg Nesterov suggested using the test to ensure we use PIDTYPE_PID
for tgid lookup also be used to avoid taking the tasklist lock.

The cost is the the same and this removes the need
to worry about complications that come from de_thread

__task_pid_nr_ns has been updated to take advantage of this change.

Switchdev notifications for addition of SWITCHDEV_OBJ_ID_PORT_VLAN are
distributed not only on clean addition, but also when flags on an
existing VLAN are changed. mlxsw_sp_bridge_port_vlan_add() calls
mlxsw_sp_port_vlan_get() to get at the port_vlan in question, which
implicitly references the object. This then leads to discrepancies in
reference counting when the VLAN is removed. spectrum.c warns about the
problem when the module is removed:

Johannes Berg says:
====================
A handful of fixes:
* missing RCU grace period enforcement led to drivers freeing
data structures before; fix from Dedy Lansky.
* hwsim module init error paths were messed up; fixed it myself
after a report from Colin King (who had sent a partial patch)
* kernel-doc tag errors; fix from Luca Coelho
* initialize the on-stack sinfo data structure when getting
station information; fix from Sven Eckelmann
* TXQ state dumping is now done from init, and when TXQs aren't
initialized yet at that point, bad things happen, move the
initialization; fix from Toke Høiland-Jørgensen.

stmmac reception handler calls stmmac_rx_vlan() to strip the vlan before
calling napi_gro_receive().
The function assumes VLAN tagged frames are always tagged with
802.1Q protocol, and assigns ETH_P_8021Q to the skb by hard-coding
the parameter on call to __vlan_hwaccel_put_tag() .
This causes packets not to be passed to the VLAN slave if it was created
with 802.1AD protocol
(ip link add link eth0 eth0.100 type vlan proto 802.1ad id 100).
This fix passes the protocol from the VLAN header into
__vlan_hwaccel_put_tag() instead of using the hard-coded value of
ETH_P_8021Q.
NETIF_F_HW_VLAN_STAG_RX check was added and the strip action is now
dependent on the correct combination of features and the detected vlan tag.
NETIF_F_HW_VLAN_STAG_RX feature was added to be in line with the driver
actual abilities.

- make sure we only allow internally generates commands in any non-live
state
- only allow connect commands on non-live queues when actually in the
new or connecting states
- treat all other non-live, non-dead states the same as a default
cach-all
This fixes a regression where we could not shutdown a controller
orderly as we didn't allow the internal generated Property Set
command, and also ensures we don't accidentally let a Connect command

Pull inode timestamps conversion to timespec64 from Arnd Bergmann:
"This is a late set of changes from Deepa Dinamani doing an automated
treewide conversion of the inode and iattr structures from 'timespec'
to 'timespec64', to push the conversion from the VFS layer into the
individual file systems.
As Deepa writes:
'The series aims to switch vfs timestamps to use struct timespec64.
Currently vfs uses struct timespec, which is not y2038 safe.
The series involves the following:
1. Add vfs helper functions for supporting struct timepec64
timestamps.
2. Cast prints of vfs timestamps to avoid warnings after the switch.
3. Simplify code using vfs timestamps so that the actual replacement
becomes easy.
4. Convert vfs timestamps to use struct timespec64 using a script.
This is a flag day patch.
Next steps:
1. Convert APIs that can handle timespec64, instead of converting
timestamps at the boundaries.
2. Update internal data structures to avoid timestamp conversions'
Thomas Gleixner adds:
'I think there is no point to drag that out for the next merge
window. The whole thing needs to be done in one go for the core
changes which means that you're going to play that catchup game
forever. Let's get over with it towards the end of the merge window'"

The reconnect path is calling the init routines to clear a queue
structure. But the queue structure has state that perhaps needs
to persist as long as the controller is live.
Remove the nvme_fc_init_queue() calls on reconnect.
The nvme_fc_free_queue() calls will clear state bits and reset
any relevant queue state for a new connection.

vfs-timespec64
Pull the timespec64 conversion from Deepa Dinamani:
"The series aims to switch vfs timestamps to use
struct timespec64. Currently vfs uses struct timespec,
which is not y2038 safe.
The flag patch applies cleanly. I've not seen the timestamps
update logic change often. The series applies cleanly on 4.17-rc6
and linux-next tip (top commit: next-20180517).
I'm not sure how to merge this kind of a series with a flag patch.
We are targeting 4.18 for this.
Let me know if you have other suggestions.
The series involves the following:
1. Add vfs helper functions for supporting struct timepec64 timestamps.
2. Cast prints of vfs timestamps to avoid warnings after the switch.
3. Simplify code using vfs timestamps so that the actual
replacement becomes easy.
4. Convert vfs timestamps to use struct timespec64 using a script.
This is a flag day patch.
I've tried to keep the conversions with the script simple, to
aid in the reviews. I've kept all the internal filesystem data
structures and function signatures the same.
Next steps:
1. Convert APIs that can handle timespec64, instead of converting
timestamps at the boundaries.
2. Update internal data structures to avoid timestamp conversions."
I've pulled it into a branch based on top of the NFS changes that
are now in mainline, so I could resolve the non-obvious conflict
between the two while merging.

Current code follows the framework that has been in the transports
from the beginning where initial link-side controller connect occurs
as part of "creating the controller". Thus that first connect fully
talks to the controller and obtains values that can then be used in
for blk-mq setup, etc. It also means that everything about the
controller is fully know before the "create controller" call returns.
This has several weaknesses:
- The initial create_ctrl call made by the cli will block for a long
time as wire transactions are performed synchronously. This delay
becomes longer if errors occur or connectivity is lost and retries
need to be performed.
- Code wise, it means there is a separate connect path for initial
controller connect vs the (same) steps used in the reconnect path.
- And as there's separate paths, it means there's separate error
handling and retry logic. It also plays havoc with the NEW state
(should transition out of it after successful initial connect) vs
the RESETTING and CONNECTING (reconnect) states that want to be
transitioned to on error.
- As there's separate paths, to recover from errors and disruptions,
it requires separate recovery/retry paths as well and can severely
convolute the controller state.
This patch reworks the fc transport to use the same connect paths
for the initial connection as it uses for reconnect. This makes a
single path for error recovery and handling.
This patch:
- Removes the driving of the initial connect and replaces it with
a state transition to CONNECTING and initiating the reconnect
thread. A dummy state transition of RESETTING had to be traversed
as a direct transtion of NEW->CONNECTING is not allowed. Given
that the controller is "new", the RESETTING transition is a simple
no-op. Once in the reconnecting thread, the normal behaviors of
ctrl_loss_tmo (max_retries * connect_delay) and dev_loss_tmo will
apply before the controller is torn down.
- Only if the state transitions couldn't be traversed and the
reconnect thread not scheduled, will the controller be torn down
while in create_ctrl.
- The prior code used the controller state of NEW to indicate
whether request queues had been initialized or not. For the admin
queue, the request queue is always created, so there's no need to
check a state. For IO queues, change to tracking whether a successful
io request queue create has occurred (e.g. 1st successful connect).
- The initial controller id is initialized to the dynamic controller
id used in the initial connect message. It will be overwritten by
the real controller id once the controller is connected on the wire.
