target: Updates from AGrover and HCH (round 3)
This patch contains a squashed version of third round series cleanups, improvements ,and simplfications from Andy and Christoph ahead of the heavy lifting between round 3 -> 4 for the target core SGL conversion. This include cleanups to the main target I/O path and other miscellaneous updates. target: Replace custom sg<->buf functions with lib funcs target: Simplify sector limiting code target: get_cdb should never return NULL target: Simplify transport_memcpy_se_mem_read_contig target: Use assignment rather than increment for t_task_cdbs target: Don't pass dma_size to generic_get_mem target: Pass sg with type scatterlist in transport_map_sg_to_mem target: Move task_sg_num next to task_sg in struct se_task target: inline struct se_transport_task into struct se_cmd target: Change name & semantics of transport_get_sectors() target: Remove unused members of se_cmd target: Rename se_cmd.t_task_cdbs to t_task_list_num target: Fix some spelling target: Remove unused var from transport_generic_do_tmr target: map_sg_to_mem: return sg_count in return value target/pscsi: Use min_t for sector limits target/pscsi: Unused param for pscsi_get_bio() target: Rename get_cdb_count to allocate_tasks target: Make transport_generic_new_cmd() available for iscsi-target target: Remove fabric callback to allocate iovecs target: Fix transport_generic_new_cmd WRITE comment (hch: Use __GFP_ZERO usage for alloc_pages() usage) Signed-off-by: Andy Grover <agrover@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
