## SECTION=system_libraries menuconfig LIBURCU tristate prompt "liburcu " select GLIBC_PTHREAD help liburcu is a LGPLv2.1 userspace RCU (read-copy-update) library. This data synchronization library provides read-side access which scales linearly with the number of cores. It does so by allowing multiples copies of a given data structure to live at the same time, and by monitoring the data structure accesses to detect grace periods after which memory reclamation is possible. if LIBURCU config LIBURCU_SMP bool prompt "SMP support" default y help Provide SMP support. Warning: Disable this only on real uniprocessor systems. endif
