Hi, This patchset is a collection of 3 changes on perf top and report tools. I wanted to make them independent, but failed due to laziness. :)
Patch 1 is a fix for -E option handling in perf top. IIUC it only shows a given number of entries. Patch 2 is a simple fix. Patch 3-5 remove a set of _threaded() functions and also remove unnecessary locking on perf report path. It leads to a small performance gain. Patch 6-9 implement a long-requested --percent-limit option. I preserve the default value to 0 but an user can set it to a different value using the .perfconfig file. You can get it from 'perf/top-v1' branch on my tree at: git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git Any comments are welcome, thanks.
