[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Linus,

The following pull request contains the first series of target-pending
patches destined for v3.4-rc1.  It contains the usual set of updates and
bugfixes to target-core + existing fabric module code, along with a
handful of the patches destined for v3.3 stable. 

Please go ahead and pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next

It also contains the necessary target-core infrastructure pieces
required to run using tcm_qla2xxx.ko WWPNs with the new Qlogic Fibre
Channel fabric module currently queued in target-pending/for-next-merge,
and coming for round 2.

The highlights for this series include:

*) Add target_submit_tmr() helper function for fabric task management (andy)
*) Convert tcm_fc to use target_submit_tmr() (andy)
*) Replace target core various cmd flags with a transport state (hch)
*) Convert loopback to use workqueue submission (hch)
*) Convert target core to use array_zalloc for tpg_lun_list (joern)
*) Convert target core to use array_zalloc for device_list (joern)
*) Add target core support for TMR_ABORT_TASK (nab)
*) Add target core se_sess->sess_kref + get/put helpers (nab)
*) Add target core se_node_acl->acl_kref for ->acl_free_comp usage (nab)
*) Convert iscsi-target to use target_put_session + sess_kref (nab)
*) Fix tcm_fc fc_exch memory leak in ft_send_resp_status (nab)
*) Fix ib_srpt srpt_handle_cmd send_ioctx->ioctx_kref leak on exception (nab)
*) Fix target core up handling of short INQUIRY buffers (roland)
*) Untangle target-core front-end and back-end meanings of max_sectors
   attribute (roland)
*) Set loopback residual field for SCSI commands (roland)
*) Fix target-core 16-bit target ports for SET TARGET PORT GROUPS emulation (roland)

Thanks again to Andy, Christoph, Joern, Roland, and everyone who has contributed
this round!
