lib: scatterlist: move SG pool code from SCSI driver to lib/sg_pool.c

2016-04-15T20:53:14Z

Now it's ready to move the mempool based SG chained allocator code from SCSI driver to lib/sg_pool.c, which will be compiled only based on a Kconfig symbol CONFIG_SG_POOL. SCSI selects CONFIG_SG_POOL. Reviewed-by: Christoph Hellwig Signed-off-by: Ming Lin Reviewed-by: Sagi Grimberg Signed-off-by: Martin K. Petersen

scsi: rename SCSI_MAX_{SG, SG_CHAIN}_SEGMENTS

2016-04-15T20:53:14Z

Rename SCSI_MAX_SG_SEGMENTS to SG_CHUNK_SIZE, which means the amount we fit into a single scatterlist chunk. Rename SCSI_MAX_SG_CHAIN_SEGMENTS to SG_MAX_SEGMENTS. Will move these 2 generic definitions to scatterlist.h later.

scsi: vpd pages are mandatory for SPC-2

2016-04-15T20:53:08Z

VPD pages 0x0 and 0x83 are mandatory even for SPC-2, so we should be lowering the restriction to avoid having to whitelist every SPC-2 compliant device. Signed-off-by: Hannes Reinecke Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K. Petersen

scsi: Add intermediate STARGET_REMOVE state to scsi_target_state

2016-04-15T20:51:53Z

Add intermediate STARGET_REMOVE state to scsi_target_state to avoid running into the BUG_ON() in scsi_target_reap(). The STARGET_REMOVE state is only valid in the path from scsi_remove_target() to scsi_target_destroy() indicating this target is going to be removed. This re-fixes the problem introduced in commits bc3f02a795d3 ("[SCSI] scsi_remove_target: fix softlockup regression on hot remove") and 40998193560d ("scsi: restart list search after unlock in scsi_remove_target") in a more comprehensive way.

scsi: disable automatic target scan

2016-04-11T20:57:09Z

On larger installations it is useful to disable automatic LUN scanning, and only add the required LUNs via udev rules. This can speed up bootup dramatically. This patch introduces a new scan module parameter value 'manual', which works like 'none', but can be overridden by setting the 'rescan' value from scsi_scan_target to 'SCSI_SCAN_MANUAL'. And it updates all relevant callers to set the 'rescan' value to 'SCSI_SCAN_MANUAL' if invoked via the 'scan' option in sysfs. Signed-off-by: Hannes Reinecke Reviewed-by: Ewan D.

scsi: Do not attach VPD to devices that don't support it

2016-04-05T10:56:40Z

The patch "scsi: rescan VPD attributes" introduced a regression in which devices that don't support VPD were being scanned for VPD attributes anyway. This could cause issues for some devices and should be avoided so the check for scsi_level has been moved out of scsi_add_lun and into scsi_attach_vpd so that all callers will not scan VPD for devices that don't support it.
