2012-02-25target: Add SCF_ACK_KREF flag for acknowledgement krefNicholas Bellinger
When TARGET_SCF_ACK_KREF is in use with target_submit_cmd() for setting the extra acknowledgement reference to se_cmd->cmd_kref, go ahead and set SCF_ACK_KREF in order to be used later by abort task.

2012-02-25target: Export transport_generic_request_failure symbolNicholas Bellinger
transport_generic_request_failure() is a wrapper around calling transport_send_check_condition_and_sense() that is required once an se_cmd->cmd_kref has been obtained via target_submit_cmd() -> target_get_sess_cmd(). tcm_qla2xxx currently requires this, and since it's necessary for other callers using target_submit_cmd() make it exportable now.

2012-02-25target: Cleanup transport_kunmap_data_sg()Andy Grover
This code isn't broken per se, but it's scary to look at! It looks like in the t_data_nents==1 case we're doing both a kunmap and a vunmap, what's saving us is that t_data_vmap in this case is 0, so vunmap doesn't do anything. Return after kunmap, so the handling of the three cases does not overlap. Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

2012-02-25target: increase iblock task sizesChristoph Hellwig
There is no real limit for task sizes in the iblock driver given that we can chain bios. Increase the maximum size to UINT_MAX, and change the code to submit bios in a smaller batch size to avoid deadlocks when having more bios in flight than the pool supports. Also increase the pool size to always allow multiple tasks to be in flight. I also had to change the task refcounting to include one reference for the submission task, which is a standard practice in this kind of code in Linux (e.g. XFS I/O submission).

2012-02-25target: replace various cmd flags with a transport stateChristoph Hellwig
Replace various atomic_ts used as flags in struct se_cmd with a single transport_state bitmap that requires t_state_lock to be held for modifications. In the target core that assumption generally is true, but some recently added code in the SRP target had to grow new lock calls. I can't say I like the way how it messes with the command state directly, but let's leave that for later. (Re-add missing ib_srpt.c changes that nab dropped..)

Here's also step one of deprecating legacy iSeries support: we are removing it from the main defconfig. Nobody seems to be using it anymore and the code is nasty to maintain, (involves horrible hacks in various low level areas of the kernel) so we plan to actually rip it out at some point.

2012-02-15regmap: Fix cache defaults initialization from raw cache defaultsLars-Peter Clausen
Currently registers with a value of 0 are ignored when initializing the register defaults from raw defaults. This worked in the past, because registers without a explicit default were assumed to have a default value of 0. This was changed in commit b03622a8 ("regmap: Ensure rbtree syncs registers set to zero properly"). As a result registers, which have a raw default value of 0 are now assumed to have no default. This again can result in unnecessary writes when syncing the cache. It will also result in unnecessary reads for e.g. the first update operation. In the case where readback is not possible this will even let the update operation fail, if the register has not been written to before. So this patch removes the check. Instead it adds a check to ignore raw defaults for registers which are volatile, since those registers are not cached.
