b1f61580fc Disable preemption when accessing current cpu id 
Currently Open CAS doesn't support kernels with involuntary preemption
anyways and once we add the support, we can get rid of this workaround

20ad0478c8 rpool: Mark an entry for kmemleak outside of atomic context 
The kmemleak_alloc() function can sleep, thus should not be called
under spinlock. This patch fixes bug occurring on debug kernel with
kmemleak enabled.

38bef1f7fe Integrate kmemleak into CAS 
Kmemleak is a tool which allows to detect memory leaks in kernel. It requires
`CONFIG_DEBUG_KMEMLEAK` to be enabled during kernel compilation. Otherwise all
the kmemleak_* functions are NOPs.
