6 | # dir: dir to look for included files | |
7 | # arch: architecture | |
8 | # files: list of files to check | |

10 | # The script reads the supplied files line by line and: | |

12 | # 1) for each include statement it checks if the | |
13 | # included file actually exists. | |
14 | # Only include files located in asm* and linux* are checked. | |
15 | # The rest are assumed to be system include files. | |
16 | # | |
17 | # 2) TODO: check for leaked CONFIG_ symbols | |
