Hello, This patchset tries to fix bugs in percentage handling which is recently changed. The perf top with symbol filter could cause a segfault (NULL pointer dereference) if the filter found no entry.
In this patchset, I moved accounting of various histogram stats to be calculated at the time it actually shown to users. Although I tested it on my system for a while, it needs more testing since it'll affect behaviors of many commands/usages. It's available at 'perf/percentage-v10' branch on my tree: git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git Any comments, review and testing are welcomed.
