ccls can't index NR_FILE_PAGES in linux kernel

[Martins3]

可以全局搜索到，但是不能 go to reference

enum cpuid_leafs
{
	CPUID_1_EDX		= 0,
	CPUID_8000_0001_EDX,
	CPUID_8086_0001_EDX,
	CPUID_LNX_1,
	CPUID_1_ECX,
	CPUID_C000_0001_EDX,
	CPUID_8000_0001_ECX,
	CPUID_LNX_2,
	CPUID_LNX_3,
	CPUID_7_0_EBX,
	CPUID_D_1_EAX,
	CPUID_LNX_4,
	CPUID_7_1_EAX,
	CPUID_8000_0008_EBX,
	CPUID_6_EAX,
	CPUID_8000_000A_EDX,
	CPUID_7_ECX,
	CPUID_8000_0007_EBX,
	CPUID_7_EDX,
	CPUID_8000_001F_EAX,
	CPUID_8000_0021_EAX,
};

似乎就是对于 enum 的成员索引有问题。

但是并不是所有的都是如此，例如这个就是没有问题的:

enum {
	/* mark page accessed */
	FOLL_TOUCH = 1 << 16,
	/* a retry, previous pass started an IO */
	FOLL_TRIED = 1 << 17,
	/* we are working on non-current tsk/mm */
	FOLL_REMOTE = 1 << 18,
	/* pages must be released via unpin_user_page */
	FOLL_PIN = 1 << 19,
	/* gup_fast: prevent fall-back to slow gup */
	FOLL_FAST_ONLY = 1 << 20,
	/* allow unlocking the mmap lock */
	FOLL_UNLOCKABLE = 1 << 21,
};

我发现 enum 也是有类似的问题
例如

union thread_union {
	struct task_struct task;
#ifndef CONFIG_THREAD_INFO_IN_TASK
	struct thread_info thread_info;
#endif
	unsigned long stack[THREAD_SIZE/sizeof(long)];
};

无法获取到 thread_union:task 或者 thread_union:: thread_info 的 reference
