Hi Linus,

I found a 3 small bugs:

* mm/slab.c: the offslab_limit calculation used 2 instead of
sizeof(kmem_bufctl_t) [==4]. Cosmetic bug, since offslab_limit is never
reached.

* expand_stack is not down_read() safe, but used in the page-in path.
Fix is trivial.

* missing/wrong lock_kernel calls in fs/fcntl.c: getlk/setlk run without
the big kernel lock. The ..64 function acquire the lock.
