在代码里用这种某某某的形式，其实也算正常；大家的感觉都是一样，如果可用形成共识，其实也是不错。
Linux Kernel里也有类似的代码：

cred.h文件里有，获取当前thread的cred里的某个成员的值，就是使用的这个某某的形式。

#define current_cred_xxx(xxx)			\
({						\current_cred()->xxx;			\
})#define current_uid()		(current_cred_xxx(uid))
#define current_gid()		(current_cred_xxx(gid))
#define current_euid()		(current_cred_xxx(euid))
#define current_egid()		(current_cred_xxx(egid))
#define current_suid()		(current_cred_xxx(suid))
#define current_sgid()		(current_cred_xxx(sgid))
#define current_fsuid() 	(current_cred_xxx(fsuid))
#define current_fsgid() 	(current_cred_xxx(fsgid))
#define current_cap()		(current_cred_xxx(cap_effective))
#define current_user()		(current_cred_xxx(user))
#define current_security()	(current_cred_xxx(security))
