- Simplify option parsing
Auto-generate getopt_long() optstring for short options from long
options array, avoiding the need to specify it manually and reducing
the surface for mistakes.
- Add unit tests
Implement unit tests (make unit-tests) using libcheck, next to
existing runtime tests (make check). Currently, three functions from
utils.c are tested.
- Add --stack-format option

Add a new model class that extends deterministic automata by adding

into account wall-clock time and as such allow RV monitor to make
assertions on real time. Add documentation and code generation

Pull ktest updates from Steven Rostedt:
- Fix undef warning when WARNINGS_FILE is unset
The check_buildlog() references WARNINGS_FILE even when it's not set.
Perl triggers a warning in this case. Check if the WARNINGS_FILE is
defined before checking if the file it represents exists.
- Fix how LOG_FILE is resolved
LOG_FILE is expanded immediately after the config file is parsed. If
LOG_FILE depends on variables from the tests it will use stale values
instead of using the test variables. Have LOG_FILE also resolve test
variables.
- Treat a undefined self reference variable as empty

Pull tracefs updates from Steven Rostedt:

Use guards() to simplify the handling of releasing locks in exit
paths.
- Use dentry name snapshots instead of allocation
Instead of allocating a temp buffer to store the dentry name to use
in mkdir() and rmdir() use take_dentry_name_snapshot().
- Fix default permissions not being applied at boot
The default permissions for tracefs was 0700 to only allow root
having access. But after a change to fix other mount options the
update to permissions ignored the defined default and used the system

Merge tag 'trace-ringbuffer-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull ring-buffer updates from Steven Rostedt:
- Add remote buffers for pKVM
pKVM has a hypervisor component that is used to protect the guest
from the host kernel. This hypervisor is a black box to the kernel as
the kernel is to user space. The remote buffers are used to have a
memory mapping between the hypervisor and the kernel where kernel may
send commands to enable tracing within the hypervisor. Then the
kernel will read this memory mapping just like user space can read
the memory mapped ring buffer of the kernel tracing system.
Since the hypervisor only has a single context, it doesn't need to
worry about races between normal context, interrupt context and NMIs
like the kernel does. The ring buffer it uses doesn't need to be as
complex. The remote buffers are a simple version of the ring buffer
that works in a single context. They are still per-CPU and use sub

Pull ftrace update from Steven Rostedt:
- Speed up ftrace_lookup_symbols() for single lookups
The kallsyms lookup in ftrace_lookup_symbols() does a linear search
over each symbol. This is fine when it must match multiple strings,
but when there's only a single string being searched for, using a
binary search is much more efficient. When a single string is passed
in to search, use the binary search method.
