git://git.kernel.org/pub/scm/linux/kernel/git/sashal/linux into core/urgent
Pull a liblockdep fix from Sasha Levin:
"A small (but important) fix to the way we detect freeing live locks. We would
pass a wrong memory region when testing for locks inside freed memory spaces,
which would trigger false positives."

In mutex destroy code currently we pass to debug_check_no_locks_freed()
[mem_from, mem_end)
address region. But debug_check_no_locks_freed() accepts
mem_from, mem_*len*
i.e. second parameter is region length, not end address. And it was
always so, starting from 2006 (fbb9ce95 "lockdep: core").
Fix it, or else on a mutex destroy we wrongly check
much-wider-than-mutex region and can find not-yet-released other locks
there and wrongly report BUGs on them.

We will use this in perf's evlist class so that it can, at
fdarray__filter() time, to unmap the associated ring buffer.
We may need to have further info associated with each fdarray entry, in
that case we'll make that int array a 'union fdarray_priv' one and put a
pointer there so that users can stash whatever they want there. For now,
an int is enough tho.
v2: Add clarification to the per array entry priv area, as well as make
it a union, which makes usage a bit longer, but if/when we make it
use more space by allowing per entry pointers existing users source
code will not have to be changed, just rebuilt.

The extensible file description array that grew in the perf_evlist class
can be useful for other tools, as it is not something that only evlists
need, so move it to tools/lib/api/fd to ease sharing it.
v2: Don't use {} like in:
libapi_dirs:
$(QUIET_MKDIR)mkdir -p $(OUTPUT){fs,fd}/
in Makefiles, as it will not work in some systems, as in ubuntu13.10.
v3: Add fd/*.[ch] to LIBAPIKFS_SOURCES (Fix from Jiri Olsa)
v4: Leave the fcntl(fd, O_NONBLOCK) in the evlist layer, remains to
be checked if it is really needed there, but has no place in the
fdarray class (Fix from Jiri Olsa)
v5: Remove evlist details from fdarray grow/filter tests. Improve it a
bit doing more tests about expected internal state.

Commit fb9edbe984 shortened held_lock->check from a 2-bit field
to a 1-bit field.
Make liblockdep compatible with the new definition by passing check=1
to lock_acquire() calls, rather than the old value check=2 (which
inadvertently disabled checks by overflowing to 0).
Without this fix, several of the test cases in liblockdep run_tests.sh
were failing.

Comparison of a boolean value (!__init_state) with a value of 2 (done)
as currently happens in the code is unlikely to succeed and causes
repeated initialization of the pthread function pointers.
Instead, remove boolean comparison so that we would initialize said

While synchronizing what's in trace-cmd vs what's in perf, I came
across a change that was made when entering the jbd2 plugin into
the tools/lib/traceevent directory. For example, one of the function
prototypes went from:
unsigned long long process_jbd2_dev_to_name(struct trace_seq *s,
unsigned long long *args)
to:
static unsigned long long
process_jbd2_dev_to_name(struct trace_seq *s,
unsigned long long *args)
I can understand the line break after the long long, but there's no
reason to keep args on a separate line.

Coming in v3.16, trace events will be able to save bitmasks in raw
format in the ring buffer and output it with the __get_bitmask() macro.
In order for userspace tools to parse this, it must be able to handle
the __get_bitmask() call and be able to convert the data that's in
the ring buffer into a nice bitmask format. The output is similar to
what the kernel uses to print bitmasks, with a comma separator every
4 bytes (8 characters).
This allows for cpumasks to also be saved efficiently.
The first user is the thermal:thermal_power_limit event which has the
following output:
thermal_power_limit: cpus=0000000f freq=1900000 cdev_state=0 power=5252

function: inotify_inode_queue_event <-- fsnotify_modify

function: __fsnotify_parent <-- fsnotify_parent
function: inotify_dentry_parent_queue_event <-- fsnotify_parent

When it's not set, it looks like:
function: fsnotify_modify

function: fsnotify_parent
function: __inc_zone_state

The traceevent plugins allows developers to have their events print out
information that is more advanced than what can be achieved by the
trace event format files.
As these plugins are used on the userspace side of the tracing tools, it
is only logical that the tools should be able to produce different types
of output for the events. The types of events still need to be defined by
the plugins thus we need a way to pass information from the tool to the
plugin to specify what type of information to be shown.
Not only does the information need to be passed by the tool to plugin, but
the plugin also requires a way to notify the tool of what options it can
provide.
This builds the plugin option infrastructure that is taken from trace-cmd
that is used to allow plugins to produce different output based on the
options specified by the tool.

Add a flag to pevent that will let the callers be able to set it and
keep the system, and perhaps even normal plugins from being loaded.
This is useful when plugins might hide certain information and seeing
the raw events shows what may be going on.

So tools/ has been growing three, at a different stage of their
development export.h headers and so we should unite into one. Add
tools/include/ to the include path of virtio and liblockdep to pick the
shared header now.

Commit 12e55569a244 "tools lib traceevent: Use helper trace-seq in print
functions like kernel does" added a extra trace_seq helper to process
string arguments like the kernel does it. But the difference between the
kernel and the userspace library is that the kernel's trace_seq structure
has a static allocated buffer. The userspace one has a dynamically
allocated one. It requires a trace_seq_destroy(), otherwise it produces
a nasty memory leak.

The return value for pevent_filter_match() is suppose to return FILTER_NONE
if the event doesn't have a filter, and FILTER_NOEXIST if there is no filter
at all. But the change 41e12e580a7 "tools lib traceevent: Refactor
pevent_filter_match() to get rid of die()" replaced the return value
with PEVENT_ERRNO__* values and added "backward compatibility" macros
that used the old names. Unfortunately, the NOEXIST and NONE macros were
swapped, and this broke users that use the old return names.

The patch 3a3ffa2e82205 ("tools lib traceevent: Report better error
message on bad function args") added the error message but it seems
there's no reason to call warning() directly.
So change it to do_warning_event() to provide event information too.

Commit 63f9a7fde7 "asmlinkage: Make lockdep_sys_exit asmlinkage" has added
asmlinkage annotation to lockdep_sys_exit, which broke build of liblockdep.
Since we don't need asmlinkage in liblockep, just ignore it.

contain '//'. It will be contained .o's in debuginfo, then confuse debugedit:
