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.

1cd1db2b45 Fully remove format nvme command 
Since there is no kernel-kernel api available to communicate
with nvme driver it is more convenient to use some nvme-dedicated
software (e.g. nvme-cli) to manage nvme devices.
It is even not possible to format nvme device with CAS using current
implementation on newest kernels.
