H A Dbuiltin-top.cb135e5ee Tue Nov 14 03:23:39 CST 2017 Jiri Olsa <jolsa@kernel.org> perf top: Fix window dimensions change handling

The stdio perf top crashes when we change the terminal
window size. The reason is that we assumed we get the
perf_top pointer as a signal handler argument which is
not the case.

Changing the SIGWINCH handler logic to change global
resize variable, which is checked in the main thread
loop.
