2006-01-14[SCSI] qla2xxx: Correct excessive delay during LOAD-RISC-RAM mailbox command.andrew.vasquez@qlogic.com
Problem report (against 2.4.x driver) from Jeff Layton <jlayton@redhat.com>: An OEM noticed that the U6 qla2200 driver would hang for around 2 minutes at boot time and then proceed normally. I found that the delay was occurring when loading the new firmware into the card, and was due to a schedule_timeout(10) added to the bottom of the polling loop. Some testing showed that the load ram operation on the card was very quick (on the order of a couple of jiffies), but the sleep in the polling loop was making each operation take around 25-30. The attached patch corrects this by making it skip sleeping during the load ram operation, since I believe we only do that when the module is plugged in. It also skips sleeping if the mbox_int flag got set during the current loop. This corrected the hang on my test setup, and OEM also confirmed that it corrected the problem for them.

2006-01-14[SCSI] qla2xxx: Use msleep() as delay during ISP polling.andrew.vasquez@qlogic.com
Mailbox commands are polled for completion during ISP initialization. During potentially 'long' mailbox commands (i.e. fabric login), we really don't want a busy-wait delay to potentially trigger a (benign) soft-lockup BUG().

2006-01-14[SCSI] iscsi: use pageslabMike Christie
From: FUJITA Tomonori <tomof@acm.org> and zhenyu.z.wang@intel.com: We cannot handle filesystems like XFS becuase of the pages they are sending us. We had thought page_count could be used to work around this, but the correct test is for PageSlab. The proper solution is to figure out what type of pages filesystems can use so we do not have to add tests like this or handle it in the block layer for all network block drivers but the issue still has not been resolved on fs-devel so we are sending this patch as a temporary fix. This is last patch just in case it is Nakd with the explanation that we need to push the correct fix through fs-devel, mm or the block layer. The rest of the patchset can live without the patch, but the driver will not work with filesystems like XFS.

2006-01-14[SCSI] iscsi: seperate iscsi interface from setup functionsMike Christie
This is the second version of the patch to address Christoph's comments. Instead of doing the lib, I just kept everything in scsi_trnapsort_iscsi.c like the FC and SPI class. This was becuase the driver model and sysfs class is tied to the session and connection setup so separating did not buy very much at this time. The reason for this patch was becuase HW iscsi LLDs like qla4xxx cannot use the iscsi class becuase the scsi_host was tied to the interface and class code. This patch just seperates the session from scsi host so that LLDs that allocate the host per some resource like pci device can still use the class. This is also fixes a couple refcount bugs that can be triggered when users have a sysfs file open, close the session, then read or write to the file.

2006-01-14[SCSI] iscsi: data digest page cache usage fixFUJITA Tomonori
Users can write to a page while we are sending it and making digest calculations. This ends up causing us to retry the command when a digest error is later reported. By using sock_no_sendpage when data digests are calculated we can avoid a lot of (not all but it helps) the retries becuase sock_no_sendpage is not zero copy.

2006-01-14[SCSI] fusion - fix pci express bugMoore, Eric
The fix is to write 'MPI_HIM_DIM' to the Host Interrupt Mask register, when enabling interrupts. Instead of the tilde of MPI_HIM_RIM. Apparently writing '1's to some of the reserved bits was causing all the bits to go to `1`, which effectly disabled all interrupts.

2006-01-14[SCSI] remove target parent limitiationChristoph Hellwig
When James Smart fixed the issue of the userspace scan atributes crashing the system with the FC transport class he added a patch to let the transport class check if the parent is valid for a given transport class. When adding support for the integrated raid of fusion sas devices we ran into a problem with that, as it didn't allow adding virtual raid volumes without the transport class knowing about it. So this patch adds a user_scan attribute instead, that takes over from scsi_scan_host_selected if the transport class sets it and thus lets the transport class control the user-initiated scanning. As this plugs the hole about user-initiated scanning the target_parent hook goes away and we rely on callers of the scanning routines to do something sensible. For SAS this meant I had to switch from a spinlock to a mutex to synchronize the topology linked lists, in FC they were completely unsynchronized which seems wrong.

2006-01-14[SCSI] I2O: move pci_request_regions() just behind pci_enable_device()Salyzyn, Mark
The problem in dpt_i2o could be the pci config space accesses it triggers as it loads, dangerous to do if there is any I/O activity going on in the other driver (probable if a boot driver I guess). I approve this patch to dpt_i2o.c, and am applying it to the Adaptec branch of the driver. Thanks for the investigation Ryoji. --- In linux 2.6.15, data transfer does hang when both dpt_i2o and i2o_block drivers are loaded. It seems that location of pci_request_regions() are wrong. I moved it just behind pci_enable_device() like other drivers, and it becomes fine. Signed-off-by: Ryoji Kamei <kamei@miraclelinux.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

LLDDs should never see REQ_BLOCK_PC requests, we can handle them just fine in the core code. There is a small behaviour change in that some check in sr's rw_intr are bypassed, but I consider the old behaviour a bug.

We need to iterate over all children when removing and expander, else stale objects will be around after host removal. This fixes the oops Eric Moore saw when removing and reloading mptsas. Also don't try the scsi_remove_target call unless operating on an end device. The current unconditional call is harmless but confusing.
