Subject: perf symbols: Store if there is a filter in place
From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>
commit 0bc2f2f7d080561cc484d2d0a162a9396bed3383 upstream.
When setting yup the symbols library we setup several filter lists,
for dsos, comms, symbols, etc, and there is code that, if there are
filters, do certain operations, like recalculate the number of non
filtered histogram entries in the top/report TUI.
But they were considering just the "Zoom" filters, when they need to
take into account as well the above mentioned filters (perf top --comms,
--dsos, etc).
So store in symbol_conf.has_filter true if any of those filters is in
place.
