Coly Li accb401220 fs/adfs: return f_fsid for statfs(2) ... 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). This patch: Make adfs return f_fsid info for statfs(2), and do a little variable renaming in adfs_statfs().
