From: Jesper Madsen <jmad@xxxxxx>
The rq_flag_bits is extended by REQ_NVM and REQ_NVM_MAPPED
REQ_NVM is used to detect request have through LightNVM on submission, and can
be detected on completion.
REQ_NVM_MAPPED is used to detect if request have mapped appropriately through
LightNVM.
The latter is added temponarily to debug the LightNVM key-value target and will
be removed later.
