      Andy Grover authored
      This does nothing, and there are many other places where
      transport_cmd_check_stop_to_fabric()'s retval is not checked>, If we
      wanted to check it here, we should probably do it those other places too.

          target: Drop iSCSI use of mutex around max_cmd_sn increment
      
      This patch fixes incorrect pr_debug() + atomic_inc_return() usage
      within iscsit_increment_maxcmdsn() code.
      
      Also fix funny iscsit_determine_maxcmdsn() usage and update
      iscsi_target_do_tx_login_io() code.

      target: Attach EXTENDED_COPY local I/O descriptors to xcopy_pt_sess · 4416f89b
      Nicholas Bellinger authored
      This patch is a >= v4.1 regression bug-fix where control CDB
      emulation logic in commit 38b57f82 now expects a se_cmd->se_sess
      pointer to exist when determining T10-PI support is to be exposed
      for initiator host ports.
      
      To address this bug, go ahead and add locally generated se_cmd
      descriptors for copy-offload block-copy to it's own stand-alone
      se_session nexus, while the parent EXTENDED_COPY se_cmd descriptor
      remains associated with it's originating se_cmd->se_sess nexus.
      
      Note a valid se_cmd->se_sess is also required for future support
      of WRITE_INSERT and READ_STRIP software emulation when submitting
      backend I/O to se_device that exposes T10-PI suport.

      target/qla2xxx: Honor max_data_sg_nents I/O transfer limit · 8f9b5654
      Nicholas Bellinger authored
      This patch adds an optional fabric driver provided SGL limit
      that target-core will honor as it's own internal I/O maximum
      transfer length limit, as exposed by EVPD=0xb0 block limits
      parameters.
      
      This is required for handling cases when host I/O transfer
      length exceeds the requested EVPD block limits maximum
      transfer length. The initial user of this logic is qla2xxx,
      so that we can avoid having to reject I/Os from some legacy
      FC hosts where EVPD=0xb0 parameters are not honored.
      
      When se_cmd payload length exceeds the provided limit in
      target_check_max_data_sg_nents() code, se_cmd->data_length +
      se_cmd->prot_length are reset with se_cmd->residual_count
      plus underflow bit for outgoing TFO response callbacks.
      It also checks for existing CDB level underflow + overflow
      and recalculates final residual_count as necessary.
      
      Note this patch currently assumes 1:1 mapping of PAGE_SIZE
      per struct scatterlist entry.

      ext4: replace open coded nofail allocation in ext4_free_blocks() · 7444a072
      Michal Hocko authored
      ext4_free_blocks is looping around the allocation request and mimics
      __GFP_NOFAIL behavior without any allocation fallback strategy. Let's
      remove the open coded loop and replace it with __GFP_NOFAIL. Without the
      flag the allocator has no way to find out never-fail requirement and
      cannot help in any way.
