OK Sure, thanks.

One question please?

I need a mutex_lock I can sleep on. Could I use the inode_lock associate
with the root_inode. Or that could lead to dead-locks with the VFS?

I'll test it out anyway, but out of your head could it lead to problems?
All I need is sleepable serialization of exofs_sync_fs() from itself.

(Or should I just allocate another mutex at the fs-sb-data?)
