+Subject: Add explicit meson thread dependency 
+Patch-mainline: mailed to mailing list
+References: none
+Signed-off-by: Tony Jones <tonyj@suse.de>
+
+Older version of meson do not add automatically the pthread dependency.
+Thus add it explicitly to the build.

-
-- Update to v1.8.0
-  * remove: add-explicit-meson-thread-dependency.patch
-  * tracefs_follow_event_clear() and tracefs_follow_missed_events_clear()
-    API to clean up followers if the tracefs instance is going to be used
-    for other iterations
-  * tracefs_instance_file_write_number()
-    A simple helper function to make it easier to write numbers into the
-    tracefs files. It does the conversion from number to string, as the
-    files expect strings and not numbers.
-  * Add API to work with kbuffer, which gives more control to the application
-    and speeds it up:
-      tracefs_cpu_read_buf()
-      tracefs_cpu_buffered_read_buf()
-      tracefs_cpu_flush_buf()
-   * tracefs_instance_get_buffer_percent() and tracefs_instance_set_buffer_percent()
-     Modify the buffer_percent file that allows readers to block until the buffer
-     is filled to a given percent. This keeps the reader from causing events that
-     will add noise to the trace.
-   * tracefs_instance_clear()
-     Helper to clear the contents of the current trace instance.
-   * tep_get_sub_buffer_data_size()
-     Helper to retrieve the current sub-buffer data size. The Linux kernel tracing
-     ring buffer is broken up into smaller sub-buffers. This returns the size of
-     the data portion of those sub-buffers (does not include the sub-buffer meta
-     data).
-   * tracefs_load_headers()
-     API to just load the information about the sub-buffers and nothing more.
-   * API to extract tracing ring buffer statistics
-       tracefs_instance_get_stat()
-       tracefs_instance_put_stat()
-       tracefs_buffer_stat_entries()
-       tracefs_buffer_stat_overrun()
-       tracefs_buffer_stat_commit_overrun()
-       tracefs_buffer_stat_bytes()
-       tracefs_buffer_stat_event_timestamp()
-       tracefs_buffer_stat_timestamp()
-       tracefs_buffer_stat_dropped_events
-    * tracefs_instance_set_subbuf_size() and tracefs_instance_get_subbuf_size()
-      API to modify the sub-buffers size of the tracing ring buffer.
-    * Added TIMESTAMP_DELTA and TIMESTAMP_DELTA_USECS to tracefs_sql() as a shortcut
-      for (end.TIMESTAMP - start.TIMESTAMP) and (end.TIMESTAMP_USECS - start.TIMESTAMP_USECS)
-      respectively
-    * Add PID filtering API:
-        tracefs_filter_pid_function()
-	tracefs_filter_pid_events()
-        tracefs_filter_pid_function_clear()
-        tracefs_filter_pid_events_clear()
-    * Added tracefs_cpu_snapshot_open() to read the raw data of snapshot buffers
-    * Added snapshot functions:
-       tracefs_snapshot_snap()
-       tracefs_snapshot_clear()
-       tracefs_snapshot_free()
-    * Added ring buffer memory mapping APIs
-      tracefs_cpu_open_mapped()
-      tracefs_cpu_is_mapped()
-      tracefs_mapped_is_supported()
-      tracefs_cpu_map()
-      tracefs_cpu_unmap()
-    * Updates:
-      - Increase pipe max size to max value when using splice.
-      - Clear "max_graph_depth" on tracefs_instance_reset()
-      - Add missing headers to syscall() and SYS_* defines
-      - Add dependency fixes to meson build
-      - Fix some documentation / man page issues
-      - Fix memory leaks
-      - Fix cscope rule
-      - Fix issues in unit tests
-      - Added many more unit tests
