I've noticed that some lock/s are using linear addresses which are located at 0xffffc901922b4500 and from what I understand from mm.txt (kernel 3.0.101): *ffffc90000000000 - ffffe8ffffffffff (=45 bits) vmalloc/ioremap space *So I'm not sure who/how/why this lock got allocated there, but obviously it is using that linear set.
