Answer: The caller to set_nmi_callback() might well have
- initialized some data that is to be used by the
- new NMI handler. In this case, the rcu_dereference()
- would be needed, because otherwise a CPU that received
- an NMI just after the new handler was set might see
- the pointer to the new NMI handler, but the old
- pre-initialized version of the handler's data.

The reason that it is permissible to use RCU list-traversal
primitives when the update-side lock is held is that doing so
can be quite helpful in reducing code bloat when common code is
- shared between readers and updaters.

10. Conversely, if you are in an RCU read-side critical section,
and you don't hold the appropriate update-side lock, you -must-
requiring SRCU's read-side deadlock immunity or low read-side
realtime latency.
- Note that, rcu_assign_pointer() and rcu_dereference() relate to
- SRCU just as they do to other forms of RCU.

is to wait until all pre-existing readers have finished before

The rcu_dereference_check() check expression can be any boolean
expression, but would normally include one of the rcu_read_lock_held()
RCU read-side critical sections, in case (2) the ->file_lock prevents
any change from taking place, and finally, in case (3) the current task
is the only task accessing the file_struct, again preventing any change

+code, it could instead be written as follows:
+
+ file = rcu_dereference_protected(fdt->fd[fd],
+ lockdep_is_held(&files->file_lock) ||
+ atomic_read(&files->count) == 1);
+
+This would verify cases #2 and #3 above, and furthermore lockdep would
+complain if this was used in an RCU read-side critical section unless one
+of these two cases held. Because rcu_dereference_protected() omits all
+barriers and compiler constraints, it generates better code than do the
+other flavors of rcu_dereference(). On the other hand, it is illegal
+to use rcu_dereference_protected() if either the RCU-protected pointer
+or the RCU-protected data that it points to can change concurrently.
There are currently only "universal" versions of the rcu_assign_pointer()
and RCU list-/tree-traversal primitives, which do not (yet) check for

DEVICE IMPLEMENTATION
A driver which supports hardware time stamping must support the
-SIOCSHWTSTAMP ioctl. Time stamps for received packets must be stored
-in the skb with skb_hwtstamp_set().
+SIOCSHWTSTAMP ioctl and update the supplied struct hwtstamp_config with
+the actual values as described in the section on SIOCSHWTSTAMP.
+
+Time stamps for received packets must be stored in the skb. To get a pointer
+to the shared time stamp structure of the skb call skb_hwtstamps(). Then
+set the time stamps in the structure:
+
+struct skb_shared_hwtstamps {
+ /* hardware time stamp transformed into duration
+ * since arbitrary point in time
+ */
+ ktime_t hwtstamp;
+ ktime_t syststamp; /* hwtstamp transformed to system time base */
+};
Time stamps for outgoing packets are to be generated as follows:
-- In hard_start_xmit(), check if skb_hwtstamp_check_tx_hardware()
- returns non-zero. If yes, then the driver is expected
- to do hardware time stamping.
+- In hard_start_xmit(), check if skb_tx(skb)->hardware is set no-zero.
+ If yes, then the driver is expected to do hardware time stamping.
- If this is possible for the skb and requested, then declare
- that the driver is doing the time stamping by calling
- skb_hwtstamp_tx_in_progress(). A driver not supporting
- hardware time stamping doesn't do that. A driver must never
- touch sk_buff::tstamp! It is used to store how time stamping
- for an outgoing packets is to be done.
+ that the driver is doing the time stamping by setting the field
+ skb_tx(skb)->in_progress non-zero. You might want to keep a pointer
+ to the associated skb for the next step and not free the skb. A driver
+ not supporting hardware time stamping doesn't do that. A driver must
+ never touch sk_buff::tstamp! It is used to store software generated
+ time stamps by the network subsystem.
- As soon as the driver has sent the packet and/or obtained a
hardware time stamp for it, it passes the time stamp back by
calling skb_hwtstamp_tx() with the original skb, the raw
- hardware time stamp and a handle to the device (necessary
- to convert the hardware time stamp to system time). If obtaining
- the hardware time stamp somehow fails, then the driver should
- not fall back to software time stamping. The rationale is that
- this would occur at a later time in the processing pipeline
- than other software time stamping and therefore could lead
- to unexpected deltas between time stamps.
-- If the driver did not call skb_hwtstamp_tx_in_progress(), then
+ hardware time stamp. skb_hwtstamp_tx() clones the original skb and
+ adds the timestamps, therefore the original skb has to be freed now.
+ If obtaining the hardware time stamp somehow fails, then the driver
+ should not fall back to software time stamping. The rationale is that
+ this would occur at a later time in the processing pipeline than other
+ software time stamping and therefore could lead to unexpected deltas
+ between time stamps.
+- If the driver did not call set skb_tx(skb)->in_progress, then
dev_hard_start_xmit() checks whether software time stamping
is wanted as fallback and potentially generates the time stamp.

+ help
+ This is VMware physical memory management driver which acts
+ like a "balloon" that can be inflated to reclaim physical pages
+ by reserving them in the guest and invalidating them in the
+ monitor, freeing up the underlying machine pages so they can
+ be allocated to other guests. The balloon can also be deflated
+ to allow the guest to use more physical memory.
+
+ If unsure, say N.
+
+ To compile this driver as a module, choose M here: the
+ module will be called vmware_balloon.
