From aae7e4534adbd96598d06e449d4f05867b0ed23f Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 6 Apr 2023 14:06:09 -0700 Subject: perf lock contention: Update total/bad stats for hidden entries When -E option is used, it only prints the given number of entries but the event stat at the end should have the numbers for entire entries. Likewise, -S option will hide entries that don't have the named function in the callstack. Also update event stat for them.
