    fs: Remove unlikely() from fput_light() · c2b3e74b
    Steven Rostedt authored
    In fput_light(), there's an unlikely(fput_needed), which running on
    my normal desktop doing firefox, xchat, evolution and part of my distcc farm,
    and running the annotate branch profiler shows that the unlikely is not
    very unlikely.
