Since tracefs will now hold the event directory for perf, and even though by default, debugfs still mounts tracefs on the debugfs/tracing directory, the system admin may now choose to not mount debugfs and instead just mount tracefs instead.

It's rather strange to be checking the debugfs MAGIC number for the tracing directory. A system admin may want to have a custom set of events to trace and it should be allowed to let the admin make a temp file (even for tracing virtual boxes, this is useful). Also with the coming tracefs, the files may not even be under debugfs, so checking the debugfs MAGIC number is pointless.

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").

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 nested vmexit events were removed from the backport from trace-cmd because they were considered buggy. They have since been updated in trace-cmd but are still missing from the traceevent library. Add back in the buggy version to be able to backport the fixes.

Allows to parse the result even if the KVM plugin does not yet understand a specific exit code.

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 Link: http://lkml.kernel.org/r/20140506132238.22e136d1@gandalf.local.homeSuggested-by: NJavi Merino <javi.merino@arm.com> Signed-off-by: NSteven Rostedt <rostedt@goodmis.org> Acked-by: NNamhyung Kim <namhyung@kernel.org> Tested-by: NJavi Merino <javi.merino@arm.com> Link: http://lkml.kernel.org/r/20140603032224.229186537@goodmis.orgSigned-off-by: NJiri Olsa <jolsa@kernel.org>

Add the options "parent" and "indent" to the function plugin. When parent is set, the output looks like this: function: fsnotify_modify <-- vfs_write function: zone_statistics <-- get_page_from_freelist function: __inc_zone_state <-- zone_statistics function: inotify_inode_queue_event <-- fsnotify_modify function: fsnotify_parent <-- fsnotify_modify function: __inc_zone_state <-- zone_statistics function: __fsnotify_parent <-- fsnotify_parent function: inotify_dentry_parent_queue_event <-- fsnotify_parent function: add_to_page_cache_lru <-- do_read_cache_page When it's not set, it looks like: function: fsnotify_modify function: zone_statistics function: __inc_zone_state function: inotify_inode_queue_event function: fsnotify_parent function: __inc_zone_state function: __fsnotify_parent function: inotify_dentry_parent_queue_event function: add_to_page_cache_lru When the otpion "indent" is not set, it looks like this: function: fsnotify_modify <-- vfs_write function: zone_statistics <-- get_page_from_freelist function: __inc_zone_state <-- zone_statistics function: inotify_inode_queue_event <-- fsnotify_modify function: fsnotify_parent <-- fsnotify_modify function: __inc_zone_state <-- zone_statistics function: __fsnotify_parent <-- fsnotify_parent function: inotify_dentry_parent_queue_event <-- fsnotify_parent function: add_to_page_cache_lru <-- do_read_cache_page Signed-off-by: NSteven Rostedt <rostedt@goodmis.org> Acked-by: NNamhyung Kim <namhyung@kernel.org> Link: http://lkml.kernel.org/r/20140603032224.056940410@goodmis.orgSigned-off-by: NJiri Olsa <jolsa@kernel.org>
