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

aa660ca0a5 Implement involuntary preemption check 
Prevent loading the kernel module if the kernel can be involuntarily
preempted

CAS will work if the kernel has been compiled with either
CONFIG_PREEMPT_NONE, CONFIG_PREEMPT_VOLUNTARY, or CONFIG_PREEMPT_DYNAMIC.
If the dynamic configuration is enabled, the kernel must be booted with
preempt=none or preempt=voluntary.

b9110635c1 cas_cache: fix "blk_update_request: operation not supported" error 
A write request with the REQ_RAHEAD flag enabled cause the nvme driver
to send a write command with access frequency value that is reserved
(at least on specification version 1.4c). NVME devices might fail this
write command with an unsupported error. So we now clear the request's
flag based on its direction.
