target: writev() on single-element vector is pointless

2013-02-26T07:46:11+00:00

... in other news:
	filp_open() can't return a struct file with NULL dentry
	filp_open() can't return a struct file negative dentry
	filp_close() of something that never had been in any descriptor
tables is pointless - fput() is all you need

target: Use TCM_NO_SENSE for initialisation

2013-01-11T04:07:10+00:00

The compiler complained about uninitialized variables, so
use TCM_NO_SENSE here.

target: Fix exception path pr_reg put regression for PR RELEASE

2012-11-08T04:12:06+00:00

Fix a regression bug in core_scsi3_emulate_pro_release() where
should still be getting released via core_scsi3_put_pr_reg() during
No persistent reservation, with returing GOOD status.

Use goto statement here to follow converted code from hch.

target: pass sense_reason as a return value

2012-11-07T04:55:46+00:00

Pass the sense reason as an explicit return value from the I/O submission
path instead of storing it in struct se_cmd and using negative return
values.  This cleans up a lot of the code pathes, and with the sparse
annotations for the new sense_reason_t type allows for much better
error checking.

(nab: Convert spc_emulate_modesense + spc_emulate_modeselect to use
      sense_reason_t with Roland's MODE SELECT changes)

target: simplify reservations code

2012-11-07T04:55:45+00:00

We do not support host-level reservations for the pscsi backend, and all
virtual backends are newere than SCSI-2, so just make the combined
SPC-3 + SCSI-2 support the only supported variant and kill the switches
for the different implementations, given that this code handles the no-op
version just fine.

target: kill struct se_subsystem_dev

2012-11-07T04:55:43+00:00

Simplify the code a lot by killing the superflous struct se_subsystem_dev.
Instead se_device is allocated early on by the backend driver, which allocates
it as part of its own per-device structure, borrowing the scheme that is for
example used for inode allocation.

2012-09-18T01:04:14+00:00

The dereference should be moved below the NULL test.

target: report too-small parameter lists everywhere

2012-09-07T18:09:08+00:00

Several places were not checking that the parameter list length
was large enough, and thus accessing invalid memory.  Zero-length
parameter lists are just a special case of this.
