ring-buffer: fix deadlock from reader_lock in read_start Impact: deadlock fix in ring_buffer_read_start The ring_buffer_iter_reset was called from ring_buffer_read_start where both grabbed the reader_lock. This patch separates out the internals of ring_buffer_iter_reset to its own function so that both APIs may grab the reader_lock.
