perf ordered_events: Add 'struct ordered_events_buffer' layer ...
When ordering events, we use preallocated buffers to store separate
events. Those buffers currently don't have their own struct, but since
they are basically an array of 'struct ordered_event' objects, we use
the first event to hold buffers data - list head, that holds all buffers
together:
struct ordered_events {
...
struct ordered_event *buffer;
...
};
struct ordered_event {
u64 timestamp;
u64 file_offset;
union perf_event *event;
struct list_head list;
};
This is quite convoluted and error prone as demonstrated by free-ing
issue discovered and fixed by Stephane in here [1].
This patch adds the 'struct ordered_events_buffer' object, that holds
the buffer data and frees it up properly.
