Changed the implementation to put mutex fast path directly inside nxsem_post, nxsem_wait and nxsem_trywait acc. to the suggestions from @xiaoxiang781216 and @pussuw . This actually gives me a huge ( ~25% ) performance boost in my real application (PX4 running in CONFIG_BUILD_KERNEL & SMP on RISC-V). The previous version gave ~10% boost. The reason is, that this optimizes all mutex paths from libc to kernel at the same take. -- This is an automated message from the Apache Git Service.
