[GIT PULL] target fixes for v3.14-rc6

[Nicholas A. Bellinger]

Hi Linus,

Here are the target-pending fixes for v3.14-rc6.

Please pull from:

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

This series addresses a number of outstanding issues wrt to active I/O
shutdown using iser-target.  This includes:

- Fix a long standing tpg_state bug where a tpg could be referenced
  during explicit shutdown (v3.1+ stable)
- Use list_del_init for iscsi_cmd->i_conn_node so list_empty checks
  work as expected (v3.10+ stable)
- Fix a isert_conn->state related hung task bug + ensure outstanding
  I/O completes during session shutdown. (v3.10+ stable)
- Fix isert_conn->post_send_buf_count accounting for RDMA READ/WRITEs
  (v3.10+ stable)
- Ignore FRWR completions during active I/O shutdown (v3.12+ stable)
- Fix command leakage for interrupt coalescing during active I/O 
  shutdown (v3.13+ stable)

Also included is another DIF emulation fix from Sagi specific to
v3.14-rc code.

Thank you,
