scsi: return blk_status_t from device handler ->prep_fn

Remove the last use of the old BLKPREP_* values, which get converted
to BLK_STS_* later anyway.

Merge branch 'fixes' into misc

2018-04-04T00:38:39+00:00

Somewhat nasty merge due to conflicts between "33b28357dd00 scsi:
qla2xxx: Fix Async GPN_FT for FCP and FC-NVMe scan" and "2b5b96473efc
scsi: qla2xxx: Fix FC-NVMe LUN discovery"

Merge is non-trivial and has been verified by Qlogic (Cavium)

scsi: scsi_dh_alua: Correct comment for alua_alloc_pg()

2018-03-15T04:32:02+00:00

In the comment for function alua_alloc_pg() the argument '@h' is
mistakenly referred to.  Fix this by replacing it with the correct
argument reference, '@tpgs', and provide a short description.

scsi: device_handler: remove VLAs

2018-03-13T02:37:20+00:00

In preparation to enabling -Wvla, remove VLAs and replace them with
fixed-length arrays instead.

scsi_dh_{alua,emc,rdac} use variable-length array declarations to store
command blocks, with the appropriate size as determined by
COMMAND_SIZE. This patch replaces these with fixed-sized arrays using
MAX_COMMAND_SIZE, so that the array size can be determined at compile
time.

This was prompted by https://lkml.org/lkml/2018/3/7/621

scsi: scsi_dh: Document alua_rtpg_queue() arguments

2018-01-31T03:26:26+00:00

Since commit 3a025e1d1c2e ("Add optional check for bad kernel-doc
comments") building with W=1 causes warnings to appear for issues in
kernel-doc headers. This patch avoids that the following warnings are
reported when building with W=1:

drivers/scsi/device_handler/scsi_dh_alua.c:867: warning: No description found for parameter 'pg'
drivers/scsi/device_handler/scsi_dh_alua.c:867: warning: No description found for parameter 'sdev'

scsi: scsi_dh_alua: skip RTPG for devices only supporting active/optimized

2018-01-11T04:25:11+00:00

For hardware only supporting active/optimized there's no point in ever
re-issuing RTPG as the only new state we can possibly read is
active/optimized.  This avoid spurious errors during path failover on
such arrays.

scsi: scsi_dh: Return SCSI_DH_XX error code from ->attach()

2017-09-25T23:03:14+00:00

Rather than having each device handler implementing their own error
mapping, have the ->attach() call return a SCSI_DH_XXX error code and
implement the mapping in scsi_dh_handler_attach().
