We've not changed anything mount related in current git* kernels,
are you sure its fixed (did it happen every time)? I'm not sure
how its XFS related too ... looks possibly lockdep related (from
*non_nested back there?) and perhaps an issue with sb->s_lock in
the kill_block_super unlock_super call?
cheers.

You are absolutely right. Oops appears only with CONFIG_DEBUG_LOCKDEP enabled.
