| H A D | spinlock.h | 345d52c1 Thu Jan 23 14:20:51 CST 2020 Qian Cai <cai@lca.pw> arm64/spinlock: fix a -Wunused-function warning
The commit f5bfdc8e3947 ("locking/osq: Use optimized spinning loop for
arm64") introduced a warning from Clang because vcpu_is_preempted() is
compiled away,
kernel/locking/osq_lock.c:25:19: warning: unused function 'node_cpu'
[-Wunused-function]
static inline int node_cpu(struct optimistic_spin_node *node)
^
1 warning generated.
Fix it by converting vcpu_is_preempted() to a static inline function.
