Currently many file systems in Linux kernel do not return f_fsid in statfs info, the value is set as 0 in vfs layer. Anyway, in some conditions, f_fsid from statfs(2) is useful, especially being used as (f_fsid, ino) pair to uniquely identify a file. Basic idea of the patches is generating a unique fs ID by huge_encode_dev(sb->s_bdev->bd_dev) during file system mounting life time (no endian consistent issue). sb is a point of struct super_block of current mounted file system being accessed by statfs(2). The patches are quite simple, any feedback or patch review is welcome.
