Subject: [PATCH 17/29] perf c2c: Increase the HITM ratio limit for displayed cachelines

From: Jiri Olsa <jolsa@...nel.org>

The cachelines being reported are the ones with percentages all the way
down to 0.05%.  That makes for very long output files. Raising that to
0.1%.  The user can always specify --show-all if they want all the
cachelines with hits.
