iSER uses the DMA mapping api to map the page holding the SCSI command data to the HCA DMA address space. When the command data is not aligned for RDMA, the data is copied to/from an allocated buffer which in turn is used for executing this command. The pages associated with the command must be unmapped before being touched. Signed-off-by: Erez Zilber <erezz@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com> |
