[PATCH 13/19] ring-buffer: Change unsigned long type of ring_buffer_oldest_event_ts() to u64

From: Yoshihiro YUNOMAE ring_buffer_oldest_event_ts() should return a value of u64 type, because ring_buffer_per_cpu->buffer_page->buffer_data_page->time_stamp is u64 type. Link: http://lkml.kernel.org/r/1349998076-15495-5-git-send-email-dhsh...@google.com Cc: Frederic Weisbecker Cc: Vaibhav
