Hi Jörg.
For my test I used latest -git of the Linux kernel.
In this version the include of ext2_fs_bh.h is guarded
by __KERNEL__ like this:
#ifdef __KERNEL__
#include <linux/ext2_fs_sb.h>
static inline struct ext2_sb_info *EXT2_SB(struct super_block *sb)
{
return sb->s_fs_info;
}
And therefore the include statement is removed in the exported set of kernel
include files.
So this particular issue is solved with the latest kernel and using the headers
prepared for export.
This tells me that we are on the right track with exporting the headers and sanitize them.
