Add possibility to supply the container name to rv list:
# rv list sched
mon1
mon2
mon3
This lists only monitors in sched, without indentation.
Supplying -h, any option (string starting with -) or more than 1
argument will still print the usage.
Passing a non-existent container prints nothing and passing no container
continues to print all monitors, showing indentation for nested
monitors, reported after their container.

RV now supports nested monitors, this functionality requires a container
monitor, which has virtually no functionality besides holding other
monitors, and nested monitors, that have a container as parent.
Add the -p flag to pass a parent to a monitor, this sets it up while
registering the monitor and adds necessary includes and configurations.
Add the -c flag to create a container, since containers are empty, we
don't allow supplying a dot model or a monitor type, the template is
also different since functions to enable and disable the monitor are not
defined, nor any tracepoint. The generated header file only allows to
include the rv_monitor structure in children monitors.

RV now supports nested monitors, this functionality requires a container
monitor, which has virtually no functionality besides holding other
monitors, and nested monitors, that have a container as parent.
Nested monitors' sysfs folders are physically nested in the container's
folder, and they are listed in the available_monitors file with the
notation container:monitor.
These changes go against the assumption that each line in the
available_monitors file correspond to a folder in the rv directory,
breaking the functionality of the rv tool.
Add support for nested containers in the rv userspace tool, indenting
nested monitors while listed and allowing both the notation with and
without container name, which are equivalent:
# rv list
mon1
mon2
container:
- nested1
- nested2
## notation with container name
# rv mon container:nested1
## notation without container name
# rv mon nested1
Either way, enabling a nested monitor is the same as enabling any other
non-nested monitor.
Selecting the container with rv mon enables all the nested monitors, if
-t is passed, the trace also includes the monitor name next to the
event:
# rv mon nested1 -t
<idle>-0 [004] event state1 x event -> state2
<idle>-0 [004] error event not expected in state2
# rv mon sched -t
<idle>-0 [004] event_nested1 state1 x event -> state2
<idle>-0 [004] error_nested1 event not expected in state2

Monitors describing complex systems, such as the scheduler, can easily
grow to the point where they are just hard to understand because of the
many possible state transitions.
Often it is possible to break such descriptions into smaller monitors,
sharing some or all events. Enabling those smaller monitors concurrently
is, in fact, testing the system as if we had one single larger monitor.
Splitting models into multiple specification is not only easier to
understand, but gives some more clues when we see errors.
Add the possibility to create container monitors, whose only purpose is
to host other nested monitors. Enabling a container monitor enables all
nested ones, but it's still possible to enable nested monitors
independently.
Add the sched monitor as first container, for now empty.

* sched_entry(bool preempt, ip)
Called while entering __schedule
* sched_exit(bool is_switch, ip)
Called while exiting __schedule
* sched_set_state(task, curr_state, state)
Called when a task changes its state (to and from running)
These tracepoints are useful to describe the Linux task model and are
adapted from the patches by Daniel Bristot de Oliveira
(https://bristot.me/linux-task-model/).

The bd_cnt field in the TX BD specifies the total number of BDs for
the TX packet. The bd_cnt field has 5 bits and the maximum number
supported is 32 with the value 0.
CONFIG_MAX_SKB_FRAGS can be modified and the total number of SKB
fragments can approach or exceed the maximum supported by the chip.
Add a macro to properly mask the bd_cnt field so that the value 32
will be properly masked and set to 0 in the bd_cnd field.
Without this patch, the out-of-range bd_cnt value will corrupt the
TX BD and may cause TX timeout.
The next patch will check for values exceeding 32.

Currently network taps unbound to any interface are linked in the
global ptype_all list, affecting the performance in all the network
namespaces.
Add per netns ptypes chains, so that in the mentioned case only
the netns owning the packet socket(s) is affected.
While at that drop the global ptype_all list: no in kernel user
registers a tap on "any" type without specifying either the target
device or the target namespace (and IMHO doing that would not make
any sense).
Note that this adds a conditional in the fast path (to check for
per netns ptype_specific list) and increases the dataset size by
a cacheline (owing the per netns lists).

The net fixed phy driver does not require the creation of a platform
device. Originally, this approach was chosen for simplicity when the
driver was first implemented.
With the introduction of the lightweight faux device interface, we now
have a more appropriate alternative. Migrate the device to utilize the
faux bus, given that the platform device it previously created was not
a real one anyway. This will get rid of the fake platform device.

Pull vfs file handling updates from Christian Brauner:
"This contains performance improvements for struct file's new refcount
mechanism and various other performance work:
- The stock kernel transitioning the file to no refs held penalizes
the caller with an extra atomic to block any increments. For cases
where the file is highly likely to be going away this is easily
avoidable.
Add file_ref_put_close() to better handle the common case where
closing a file descriptor also operates on the last reference and
build fput_close_sync() and fput_close() on top of it. This brings
about 1% performance improvement by eliding one atomic in the
common case.
- Predict no error in close() since the vast majority of the time
system call returns 0.
- Reduce the work done in fdget_pos() by predicting that the file was
found and by explicitly comparing the reference count to one and
ignoring the dead zone"

Pull vfs afs updates from Christian Brauner:
"This contains the work for afs for this cycle:
- Fix an occasional hang that's only really encountered when
rmmod'ing the kafs module
- Remove the "-o autocell" mount option. This is obsolete with the
dynamic root and removing it makes the next patch slightly easier
- Change how the dynamic root mount is constructed. Currently, the
root directory is (de)populated when it is (un)mounted if there are
cells already configured and, further, pairs of automount points
have to be created/removed each time a cell is added/deleted
This is changed so that readdir on the root dir lists all the known
cell automount pairs plus the @cell symlinks and the inodes and
dentries are constructed by lookup on demand. This simplifies the
cell management code
- A few improvements to the afs_volume and afs_server tracepoints
- Pass trace info into the afs_lookup_cell() function to allow the
trace log to indicate the purpose of the lookup
- Remove the 'net' parameter from afs_unuse_cell() as it's
superfluous
- In rxrpc, allow a kernel app (such as kafs) to store a word of
information on rxrpc_peer records
- Use the information stored on the rxrpc_peer record to point to the
afs_server record. This allows the server address lookup to be done
away with
- Simplify the afs_server ref/activity accounting to make each one
self-contained and not garbage collected from the cell management
work item
- Simplify the afs_cell ref/activity accounting to make each one of
these also self-contained and not driven by a central management
work item
The current code was intended to make it such that a single timer
for the namespace and one work item per cell could do all the work
required to maintain these records. This, however, made for some
sequencing problems when cleaning up these records. Further, the
attempt to pass refs along with timers and work items made getting
it right rather tricky when the timer or work item already had a
ref attached and now a ref had to be got rid of"

The context indicates that 'than' is the correct word instead of 'then',
as a comparison is being performed.
Given that 'then' is also a valid English word, checkpatch.pl wouldn't
have picked up on this spelling error.
