[lttng-dev] [RFC PATCH liburcu] urcu-bp: introduce urcu_bp_disable_sys_membarrier()

[Norbert Lange]

I still would like to propose having a compile time "off switch",
cant see how this would work with preloaded libraries for one
(lttng itself whips with multiple)

Cant tell for sure now, but a setup where "bulletproof Xenomai"
libraries are used seems to better than special setup magic.
If you have to do do alot measurements for finding rare hiccups,
the last thing you want it figuring out you forget one config.

Thanks for the speedy support, Norbert
