This series improves ring_buffer.c by changing the type of some
static functions to void or bool and uses try_cmpxchg instead of
cmpxchg (*ptr, old, new) == old where appropriate.

v2: Convert only loops with cmpxchg.
v3: Rearrange variable declarations.
v4: Change ret in rb_get_reader_page.
    Rearrange variable declarations.
