Subject: [PATCH] code cleanup on include/linux/fs.h

Hi all,

Can this patch be fixed in,

Cleanup the unsed code on include/linux/fs.h.
All filesystem using mount_bdev and mount_nodev
to replace get_sb_bdev and get_sb_nodev.
So rmmove the unused code.

The functions themselves are still in place, what's up?

fs/super.c:846:int get_sb_bdev(struct file_system_type *fs_type,
fs/super.c:861:EXPORT_SYMBOL(get_sb_bdev);
