Does it make sense to create a header file that contains only "struct ....;"
lines? A lot of "struct ....;" lines are used for avoiding compiler warning.
This results in LXR (linux cross reference) showing like

Defined as a struct type in:

    * security/selinux/include/avc.h, line 35
    * fs/udf/udfdecl.h, line 78
    * fs/isofs/isofs.h, line 108
    * fs/gfs2/bmap.h, line 15
    * fs/gfs2/dir.h, line 16
    * fs/xfs/xfs_acl.h, line 21
    * fs/xfs/xfs_vnodeops.h, line 7
    * fs/freevxfs/vxfs_extern.h, line 44
    * include/linux/net.h, line 67
    * include/linux/exportfs.h, line 7
    * include/linux/seq_file.h, line 13
    * include/linux/mm.h, line 245
    * include/linux/syscalls.h, line 16

    * include/linux/cdev.h, line 9

    * include/linux/mtd/blktrans.h, line 31
    * include/linux/generic_acl.h, line 6
    * include/linux/futex.h, line 127 

and makes it difficult to find the location of actual definition.
