[PATCH 3.16 168/233] perf script python: Updated trace_unhandled() signature

[Ben Hutchings]

3.16.48-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: SeongJae Park <sj38.park@xxxxxxxxx>

commit 1bf8d5a4a5da19b1f6e7958fe67db4118fa7a1c1 upstream.

Default function signature of trace_unhandled() got changed to include a
field dict, but its documentation, perf-script-python.txt has not been
updated.  Fix it.
