This patch contains the squashed version of forth round series cleanups from Andy and Christoph following the post heavy lifting in the preceeding: 'Eliminate usage of struct se_mem' and 'Make all control CDBs scatter-gather' changes. This also includes a conversion of target core and the v3.0 mainline fabric modules (loopback and tcm_fc) to use pr_debug and the CONFIG_DYNAMIC_DEBUG infrastructure! These have been squashed into this third and final round for v3.1. target: Remove ifdeffed code in t_g_process_write target: Remove direct ramdisk code target: Rename task_sg_num to task_sg_nents target: Remove custom debug macros for pr_debug. Use pr_err(). target: Remove custom debug macros in mainline fabrics target: Set WSNZ=1 in block limits VPD. Abort if WRITE_SAME sectors = 0 target: Remove transport do_se_mem_map callback target: Further simplify transport_free_pages target: Redo task allocation return value handling target: Remove extra parentheses target: change alloc_task call to take *cdb, not *cmd (nab: Fix bogus struct file assignments in fd_do_readv and fd_do_writev) Signed-off-by: Andy Grover <agrover@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
