Subject: [PATCH v15 02/12] tools lib fd array: Allow associating a pointer cookie with each entry
Date: Tue, 12 Jul 2016 10:00:02 +0000 [thread overview]
Message-ID: <1468317612-11598-3-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1468317612-11598-1-git-send-email-wangnan0@huawei.com>
Add a 'ptr' field to fdarray->priv array.
This feature will be used by following commits, which introduce muiltiple
'struct perf_mmap' array for different types of mapping. Because of this,
during fdarray__filter(), a simple 'idx' is not enough. Add a pointer cookie
allows directly associate a 'struct perf_mmap' pointer to an fdarray entry.
