[GIT PULL] target: Updates for v3.2-rc1 (round two)

[GIT PULL] target: Updates for v3.2-rc1 (round two)

[Nicholas A. Bellinger]

Hi Linus,

The following is the second round of target core updates for the v3.2
merge window.  Please go ahead and pull from:

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

A separate PULL request for the ib_srpt fabric merge will be going out
shortly.

This series includes:

*) Bugfixes from Joern for TMR processing during LUN_RESET handling
*) Bugfix for tcm_loop to explictly clear control CDB READ payload
*) Conversion of TFO->check_stop_free to return status as a hint to
   LUN_RESET processing
*) Removal of TRANSPORT_FREE_CMD_INTR in favor of per fabric release
   workqueues
*) Initial pieces of generic active I/O shutdown tracking.  (Will be enabled
   for ib_srpt in a seperate patch)
*) Convert control CDB code to pass se_task into CDB emulation callback
*) Refactoring of CDB emulation from Christoph to universally use
   cmd->execute_task()

The generic active I/O shutdown bits and ->execute_task conversion got
in a bit late, but I still think are suitable v3.2 material.  Also, we
have one more bugfix+cleanup patch to remove legacy PYX_TRANSPORT_*
return code usage still being discussed, and will be sent out post merge
window to address existing breakage with se_cmd->scsi_sense_reason
assignment and errno return code conversion.

Thanks!

Hi Linus,

This is just a friendly reminder to please pull the two remaining
target-pending branches (for-next and for-next-merge) for -rc1.

Thank you,

Thanks for pulling the target core changes from target-pending/for-next.

Please also consider pulling the new ib_srpt driver in for-next-merge
here:

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

We are making forward progress on the remaining items to be included in
the next rc-fixes pull, but please consider the last GIT PULL request
below for an initial merge with what we have collectively agreed upon
for the userspace API in /sys/kernel/config/target/srpt for v3.2.

[GIT PULL] ib_srpt: Initial SRP Target merge for v3.2-rc1
