From 258e4bfcbdaa6d128c391e6e25f03d54dee4f226 Mon Sep 17 00:00:00 2001 From: Wang Nan <wangnan0@huawei.com> Date: Wed, 25 May 2016 13:44:57 +0000 Subject: tools: Pass arg to fdarray__filter's call back function Before this patch there's no way to pass arguments to fdarray__filter's call back function. This improvement will be used by 'perf record' to support unmapping ring buffer for both main evlist and overwrite evlist. Without this patch there's no way to track overwrite evlist from 'struct fdarray'.
