Aye, for further edification, Baole, please read include/linux/stat.h,
particularly this part:
#define S_IRWXUGO (S_IRWXU|S_IRWXG|S_IRWXO)
#define S_IALLUGO (S_ISUID|S_ISGID|S_ISVTX|S_IRWXUGO)
#define S_IRUGO (S_IRUSR|S_IRGRP|S_IROTH)
#define S_IWUGO (S_IWUSR|S_IWGRP|S_IWOTH)
#define S_IXUGO (S_IXUSR|S_IXGRP|S_IXOTH)
I suspect many of the patches in this set should be using one of the above
defines instead, never mind the ridiculousness of firing off such a
massive set at once, with every patch having the same (often not correct)
title, and the highly questionable benefit of the set to begin with.
