[RFC PATCH 0/2] kbuild: use relative path from $(srctree) instead of __FILE__

[Masahiro Yamada]

Kbuild works in objtree, not in srctree.  So, __FILE__ is prefixed
with $(srctree)/ for out-of-tree build.

It would be nice to see the same log regardless
in-tree, or out-of-tree build.

1/2 adds a new macro KBUILD_FILE.  This points the relative path
of the file we are building.  This is intended to replace __FILE__.

2/2 replaces __FILE__ in bug.h as an example.  This will improve
the output of WARN_ON() etc.



Masahiro Yamada (2):
  kbuild: add KBUILD_FILE to point relative file path from $(srctree)
  bug.h: replace __FILE__ with KBUILD_FILE for shorter names in log
