From 2b4383470675c85add72725cc08840d36b409276 Mon Sep 17 00:00:00 2001 From: Wang Nan Date: Thu, 14 Jul 2016 08:34:34 +0000 Subject: tools lib fd array: Allow associating a pointer cookie with each entry Add a 'ptr' field to fdarray->priv array. This feature will be used by following commits, which introduce muiltiple 'struct perf_mmap' arrays for different types of mapping. Because of this, during fdarray__filter(), a simple 'idx' is not enough. Add a pointer cookie that allows to directly associate a 'struct perf_mmap' pointer to an fdarray entry.
