Arnaldo Carvalho de Melo 2171a92568 tools lib fd array: Allow associating an integer cookie with each entry ... We will use this in perf's evlist class so that it can, at fdarray__filter() time, to unmap the associated ring buffer. We may need to have further info associated with each fdarray entry, in that case we'll make that int array a 'union fdarray_priv' one and put a pointer there so that users can stash whatever they want there. For now, an int is enough tho. v2: Add clarification to the per array entry priv area, as well as make it a union, which makes usage a bit longer, but if/when we make it use more space by allowing per entry pointers existing users source code will not have to be changed, just rebuilt.
