I did following:
1. To start with linux-2.6.19-rc2-orig and linux-2.6.19-rc2 are
identical
2. cd linux-2.6.19-rc2; make allmodconfig; make
3. diff -uprN -X linux-2.6.19-rc2-orig/Documentation/dontdiff
linux-2.6.19-rc2-orig linux-2.6.19-rc2 > /tmp/patch
The above generates 2MB patch file. What is wrong ?
It seems a new folder is created: linux-2.6.19-rc2/usr/include
diff -uprN -X linux-2.6.19-rc2-orig/Documentation/dontdiff linux-2.6.19-rc2-orig/usr/include/asm-generic/atomic.h linux-2.6.19-rc2/usr/include/asm-generic/atomic.h
