Subject[PATCH 12/22] Inline buffered_rmqueue()
buffered_rmqueue() is in the fast path so inline it. Because it only has one
call site, this function can then be inlined without causing text bloat. On
an x86-based config, it made no difference as the savings were padded out
by NOP instructions. Milage varies but text will either decrease in size
or remain static.
