The change of devlink_alloc() to accept device makes sure that device
is fully initialized and device_register() does nothing except allowing
users to use that devlink instance.

Such change ensures that no user input will be usable till that point and
it eliminates the need to worry about internal locking as long as devlink_register
is called last since all accesses to the devlink are during initialization.

This change fixes the following lockdep warning.

The liquidio driver is broken by design. It initialize PCI devices
in separate delayed works. It causes to the situation where device lock
is dropped during initialize and remove sequences.

That lock is part of driver/core and needed to protect from races during
init, destroy and bus invocations.

In addition to lack of locking protection, it has incorrect order of
destroy flows and very questionable synchronization scheme based on
atomic_t.

This change doesn't fix that driver but makes sure that rest of the
netdev subsystem doesn't suffer from such basic protection by adding
device_lock over devlink_*() APIs and by moving devlink_register()
to be last command in setup_nic_devices().

The purpose of this test is to verify that after a short activity passes,
the reported time is reasonable: not zero (which could be reported by
mistake), and not something outrageous (which would be indicative of an
issue in used units).

However, the idle time is reported in units of clock_t, or hundredths of
second. If the initial sequence of commands is very quick, it is possible
that the idle time is reported as just flat-out zero. When this test was
recently enabled in our nightly regression, we started seeing spurious
failures for exactly this reason.

Therefore buffer the delay leading up to the test with a sleep, to make
sure there is no legitimate way of reporting 0.

mptcp: Miscellaneous fixes

Here are five changes we've collected and tested in the mptcp-tree:

Patch 1 changes handling of the MPTCP-level snd_next value during the
recovery phase after a subflow link failure.

Patches 2 and 3 are some small refactoring changes to replace some
open-coded bits.

Patch 4 removes an unused field in struct mptcp_sock.

Patch 5 restarts the MPTCP retransmit timer when there is
not-yet-transmitted data to send and all previously sent data has been
acknowledged. This prevents some sending stalls.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

The retransmit head will be NULL in case there is no in-flight data
(meaning all data injected into network has been acked).

In that case the retransmit timer is stopped.

This is only correct if there is no more pending, not-yet-sent data.

If there is, the retransmit timer needs to set the PENDING bit again so
that mptcp tries to send the remaining (new) data once a subflow can accept
more data.

Also, mptcp_subflow_get_retrans() has to be called unconditionally.

This function checks for subflows that have become unresponsive and marks
them as stale, so in the case where the rtx queue is empty, subflows
will never be marked stale which prevents available backup subflows from
becoming eligible for transmit.

The update on recovery is not correct.

will update tx_pending_data multiple times when a subflow is declared
stale while earlier recovery is still in progress.
This means that tx_pending_data will still be positive even after
all data as has been transmitted.

Rather than fix it, remove this field: there are no consumers.
The outstanding data byte count can be computed either via

 "msk->write_seq - rtx_head->data_seq" or
 "msk->write_seq - msk->snd_una".

The latter is more recent/accurate estimate as rtx_head adjustment
is deferred until mptcp lock can be acquired.

We have a few more places where the mptcp code duplicates
lockdep_assert_held_once(). Let's use the existing macro and
avoid a bunch of compiler's conditional.

When recovering after a link failure, snd_nxt should not be set to a
lower value.  Else, update of snd_nxt is broken because:

  msk->snd_nxt += ret; (where ret is number of bytes sent)

assumes that snd_nxt always moves forward.
After reduction, its possible that snd_nxt update gets out of sync:
dfrag we just sent might have had a data sequence number even past
recovery_snd_nxt.

This change factors the common msk state update to a helper
and updates snd_nxt based on the current dfrag data sequence number.

The conditional is required for the recovery phase where we may
re-transmit old dfrags that are before current snd_nxt.

After this change, snd_nxt only moves forward and covers all in-sequence
data that was transmitted.

recovery_snd_nxt is retained to detect when recovery has completed.
