[1] In-tree build (without O=...)
[2] Out-of-tree build and the build directory is right under the source tree
For example, O=foo
[3] Out-of-tree build and the build directory is not right under the source tree
For example, O=foo/bar or O=../foo
__FILE__ points to the source file in relative path for [1] and [2],
and in absolute path for [3].
I guess you are doing [3]. Just try [1] or [2].
FYI, the relative/absolute path is determined by "srctree" of the top Makefile.
ifeq ($(KBUILD_SRC),)
# building in the source tree
srctree := .
else
ifeq ($(KBUILD_SRC)/,$(dir $(CURDIR)))
# building in a subdirectory of the source tree
srctree := ..
else
srctree := $(KBUILD_SRC)
endif
endif
