- Userspace implementation of the Read-Copy-Update (RCU)
- synchronization mechanism. This library is mainly used by
- the LTTng tracing infrastructure, but can be used for other
- purposes as well.
- On ARM, because of bug:
- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58854
- liburcu cannot be built using gcc 4.8.0, 4.8.1 or 4.8.2
- without the following bug fix:
- http://gcc.gnu.org/viewcvs/gcc?view=revision&revision=204665
- http://lttng.org/urcu
- comment "liburcu needs a toolchain w/ threads"
- depends on BR2_PACKAGE_LIBURCU_ARCH_SUPPORTS
- depends on !BR2_TOOLCHAIN_HAS_THREADS
