Hi,

likely()/unlikely() seems to be amongst the last macros that urcu
defines that don't have urcu-specific prefixes. Thoughts on whether we
should add a prefix such as caa_likely() and caa_unlikely() are welcome.

Thanks,

Mathieu

In our usage of liburcu, I had to do macro whacking to workaround
this conflict.  Even wrapping the definition in urcu with '#ifndef likely'
would help.

OK. I'll rename likely/unlikely to caa_likely/caa_unlikely.

commit a0b7f7ea3fc3339a1c42caffd53ce9f056e5b901
Author: Mathieu Desnoyers <mathieu.desnoyers at efficios.com>

    Rename likely/unlikely to caa_likely/caa_unlikely
    
    This fixes namespace conflicts.
