2008-02-07[SCSI] arcmsr: updates (1.20.00.15)Nick Cheng
- add arcmsr_enable_eoi_mode()and readl(reg->iop2drv_doorbell_reg) in arcmsr_handle_hbb_isr() on adapter Type B in case of the doorbell interrupt clearance is cached - add conditional declaration for arcmsr_pci_error_detected() and arcmsr_pci_slot_reset - check if the sg list member number exceeds arcmsr default limit in arcmsr_build_ccb() - change the returned value type of arcmsr_build_ccb()from "void" to "int" returns FAILED in arcmsr_queue_command() - modify arcmsr_drain_donequeue() to ignore unknown command and let kernel process command timeout. This could handle IO request violating maximum segments, i.e. Linux XFS over DM-CRYPT. Thanks to Milan Broz's comments <mbroz@redhat.com> - fix the release of dma memory for type B in arcmsr_free_ccb_pool() - fix the arcmsr_polling_hbb_ccbdone() Signed-off-by: Nick Cheng <nick.cheng@areca.com.tw> Cc: Milan Broz <mbroz@redhat.com> Cc: <thenzl@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

2008-02-07[SCSI] qla2xxx: Access the proper 'physical' port in FC-transport callbacks.Seokmann Ju
For following fc_host specific attributes, vports rely on the pport.

2008-02-07[SCSI] qla2xxx: Correct resource_size_t usages.Andrew Vasquez
Hmm, it looks like the conversion to resource_size_t usage (3776541d8a46347a4924353a192c6ce4a3d04e2e) requires some additional fixups to cleanup the structure-pointer castings used during IO mapped accesses to the chip. There's only a small number of locations, where the driver uses IO mapped accesses to the hardware, the patch below should take care of it without introducing to many structural changes to code flow.

2008-02-07[SCSI] libiscsi: fix session age rollover and remove cid encodingMike Christie
The session age mask is only 4 bits, but session->age is 32. When it gets larger then 15 and we try to or the bits some bits get dropped and the check for session age in iscsi_verify_itt is useless. The ISCSI_CID_MASK related bits are also useless since cid is always one. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2008-02-07[SCSI] iscsi: fix up iscsi printk prefixMike Christie
Some iscsi class messages have the dev_printk prefix and some libiscsi and iscsi_tcp messages have "iscsi" or the module name as a prefix which is normally pretty useless when trying to figure out which session or connection the message is attached to. This patch adds iscsi lib and class dev_printks so all messages have a common prefix that can be used to figure out which object printed it.

2008-02-07[SCSI] qla4xxx: add async scan supportMike Christie
qla4xxx has the old school startup/probe where it finds presetup sessions in its flash and then attempts to log into them before returning from the probe. This however, makes it very simple to add a iscsi class scan finished helper which the driver can use. In future patches Dave or I will rip apart the driver to make it more like qla2xxx, but for now this is a very simple two line patch which fixes the problem of trying to figure out when the initial sessions are done being scanned.

2008-02-07[SCSI] iscsi class: add async scan helperMike Christie
In qla4xxx's probe it will call the iscsi session setup functions for session that got setup on the initial start. This then makes it easy for the iscsi class to export a helper which indicates when those scans are done.

2008-02-07[SCSI] qla4xxx: fix recovery timer and session unblock raceMike Christie
If qla4xxx is resetting up a session and the recovery timer fires we do not want to just set it to dead, because the dpc thread could have just set it to online and is in the middle of resetting it up.

2008-02-07[SCSI] iscsi class: add session scanningMike Christie
This just adds iscsi session scanning which works like fc rport scanning. The future patches will hook the drivers into Mathew Wilcox's async scanning infrastructure, so userspace does not have to special case iscsi and so userspace does not have to make a extra special case for hardware iscsi root scanning.

2008-02-07[SCSI] qla4xxx: use iscsi class session state check readyMike Christie

2008-02-07[SCSI] qla4xxx: directly call iscsi recovery functionsMike Christie
Qla4xxx can just call the iscsi recovery functions directly. There is no need for userspace to do this for qla4xxx, because we do not use the mutex to iterate over devices anymore and iscsi_block /unblock_session can be called from interrupt context or the dpc thread. And having userspace do this just creates uneeded headaches for qla4xxx root situations where the session may experience problems. For example during the kernel shutdown the scsi layer wants to send sync caches, but at this time userspace is not up (iscsid is not running), so we cannot recover from the problem.

2008-02-07[SCSI] ps3rom: sector size should be 512 bytesAegis Lin
It should be desired that 64 KiB is available for ATAPI transferrring. (Historically) in SCSI/block layer sector size is defined as 512 during sector-byte calculation. Originally in ps3rom.c CD_FRAMESIZE (2048) was used, which limited /sys/block/sr0/queue/max_sectors_kb to 16 KiB (32 sectors).
