2 #
3 # headers_check.pl execute a number of trivial consistency checks
4 #
5 # Usage: headers_check.pl dir [files...]
6 # dir: dir to look for included files
7 # arch: architecture
8 # files: list of files to check
9 #
10 # The script reads the supplied files line by line and:
11 #
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
