[Lustre-discuss] Why does lustre use 2 SUPER_MAGIC ?

[Maxence Dunnewind]

Heya,

I saw in lustre code that it uses 2 SUPER__MAGIC : 
 - LUSTRE_SUPER_MAGIC = 0x0BD00BD1
 - LL_SUPER_MAGIC = 0x0BD00BD0

It seems most of the files are using the first one as s_magic
(file->f_entry->f_sb->s_magic).

What's the difference between them, when each is used ? 

Regards,

Maxence
