参考Indent style，这里讲，
K&R style
The K&R style, so-called because it was used in Kernighan and Ritchie's book The C Programming Language, is commonly used in C. ...
Advocates of this style sometimes refer to it as "The One True Brace Style" (abbreviated as 1TBS or OTBS) because of the precedent set by C (although advocates of other styles have been known to use similarly strong language). The source code of the Unix kernel and Linux kernel are written in this style.
找到那本书：里面关于“_”的部分：
1）The underscore ``_'' counts as a letter; it is sometimes useful for improving the readability of long variable names. Don't begin variable names with underscore, however, since library routines often use such names.
2）In the following excerpt from a typical , names that are intended for use only by functions of the library begin with an underscore so they are less likely to collide with names in a user's program. This convention is used by all standard library routines.
3）External identifiers that begin with an underscore are reserved for use by the library, as are all other identifiers that begin with an underscore and an upper-case letter or another underscore.
从上面看来，可以理解为，带下划线开头的，仅仅用作一个模块或者内核内部使用吧
不知道有没有其他解释?
