    For Linux userspace rseq, see the standalone library and the GLIBC integration. Note that there's the major downside of a fallback being mandatory, and also the downside of the compiler being ignorant, unlike kernel or segment/TLS cpu-locals.

    The epoch GC library I've used before was a Google-internal C++ one. It noticeably improved my software's tail latency over rwlocks. The unique thing about it is that it was basically zero-cost over a plain non-atomic pointer. It used Linux restartable sequences (aka rseq) to take advantage of synchronization operations Linux does on each context switch, rather than adding new atomics. I'm not aware of any open source synchronization libraries that do the same thing, but there's nothing stopping someone from writing one. rseq kernel support has been in mainline since Linux 4.18.
