linux.git/drivers/target/sbp, branch v3.10.76

Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending

2013-03-02T19:43:27+00:00

Pull SCSI target patches from Nicholas Bellinger:
 "Here are the remaining target-pending patches for v3.9-rc1.

  The most important one here is the immediate queue starvation
  regression fix for iscsi-target, which addresses a bug that's
  effecting v3.5+ kernels under heavy sustained READ only workloads.
  Thanks alot to Benjamin Estrabaud for helping to track this down!

  Also included is a pSCSI exception bugfix from Asias, along with a
  handful of other minor changes.  Both bugfixes are CC'ed to stable."

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
  target/pscsi: Rename sg_num to nr_vecs in pscsi_get_bio()
  target/pscsi: Fix page increment
  target/pscsi: Drop unnecessary NULL assignment to bio->bi_next
  target: Add __exit annotation for module_exit functions
  iscsi-target: Fix immediate queue starvation regression with DATAIN

target: Add __exit annotation for module_exit functions

2013-02-28T03:12:10+00:00

Inclues sbp_exit, fileio_module_exit, iblock_module_exit and
pscsi_module_exit.

Note: rd_module_exit() can not be annotated by __exit, becasue it is
called by target_core_init_configfs() which is annotated by __init.

sbp-target: fix error path in sbp_make_tpg()

2012-12-13T05:17:25+00:00

If the TPG memory is allocated successfully, but we fail further along
in the function, a dangling pointer to freed memory is left in the TPort
structure. This is mostly harmless, but does prevent re-trying the
operation without first removing the TPort altogether.

sbp-target: use simple assignment in tgt_agent_rw_agent_state()

2012-12-13T05:16:47+00:00

There is no need to memcpy() a 32-bit integer. The data pointer is
guaranteed to be quadlet aligned by the FireWire stack so we can replace
the memcpy() with an assignment.

Thanks to Stefan Richter.

sbp-target: remove depends on CONFIG_EXPERIMENTAL

2012-11-08T04:12:09+00:00

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

sbp-target: fix return value check in sbp_register_configfs()

2012-09-22T23:29:52+00:00

In case of error, the function target_fabric_configfs_init() returns
ERR_PTR() not NULL pointer. The NULL test in the return value check
should be replaced with IS_ERR().

target: Simplify fabric sense data length handling

2012-09-18T00:12:58+00:00

Every fabric driver has to supply a se_tfo->set_fabric_sense_len()
method, just so iSCSI can return an offset of 2.  However, every fabric
driver is already allocating a sense buffer and passing it into the
target core, either via transport_init_se_cmd() or target_submit_cmd().

So instead of having iSCSI pass the start of its sense buffer into the
core and then later tell the core to skip the first 2 bytes, it seems
easier for iSCSI just to do the offset of 2 when it passes the sense
buffer into the core.  Then we can drop the se_tfo->set_fabric_sense_len()
everywhere, and just add a couple of lines of code to iSCSI to set the
sense data length to the beginning of the buffer right before it sends
it over the network.

(nab: Remove .set_fabric_sense_len usage from tcm_qla2xxx_npiv_ops +
      change transport_get_sense_buffer to follow v3.6-rc6 code w/o
      ->set_fabric_sense_len usage)
