From 5cdde5c25a0e71d923a6d56e5c94e058887f95d8 Mon Sep 17 00:00:00 2001 From: jaszha03 Date: Thu, 11 Jul 2019 20:47:24 +0000 Subject: vppinfra: refactor test_and_set spinlocks to use clib_spinlock_t Spinlock performance improved when implemented with compare_and_exchange instead of test_and_set. All instances of test_and_set locks were refactored to use clib_spinlock_t when possible. Some locks e.g. ssvm synchronize between processes rather than threads, so they cannot directly use clib_spinlock_t.
