2007-04-30[SCSI] fusion: fix domain validation loopsEric Moore2-2/+22
After host reset, the device are programmed to default asyn narrow nego. We need to reprogram the parameter back to previous values. If the host reset is called as a result of spi_dv_device() commands timing out, its possible to get into an infinite loop of dv to host reset. This will prevent that case, as we merely program old values. If host reset is called outside context of domain validation, then we can call spi_dv_device.

2007-03-27[PATCH] i2o: block IO errors on i2o diskVasily Averin1-11/+1
I2O subsystem has been broken in mainstream several months ago (after 2.6.18). Commit 4aff5e2333c9a1609662f2091f55c3f6fffdad36 from Jens Axboe split struct request ->flags into two parts: cmd_type and cmd_flags. In i2o layer this patch has replaced flag REQ_SPECIAL by the according cmd_type. However i2o has used REQ_SPECIAL not as command type but as driver-specific flag for the debug purposes. As result all i2o requests have type "special" now, are not processed to the hardware and fail with I/O error: i2o/hda:<3>Buffer I/O error on device i2o/hda, logical block 0 Buffer I/O error on device i2o/hda, logical block 0 Buffer I/O error on device i2o/hda, logical block 0 unable to read partition table block-osm: device added (TID: 207): i2o/hda The following patch removes the extra debug checks without any drawbacks and restores the normal driver's work.

2007-03-20[SCSI] fusion: remove VMWare guest OS remounted as read only work aroundEric Moore1-4/+1
This address the issue of VMWare guest OS being remounted as read-only becuase the underlying device was held busy too long and at the same time address Engenio MPP driver concerns over infinite retries. This patch removes the code that snoops the SAM STATUS on busy, which would be returning DID_BUS_BUSY, instead we return the status as is. Retry hanlding seems to be properly handled in scsi_softirq_done, where a busy sam status would only occurr for the time specified by (cmd->allowed +1) * cmd->timeout_per_command.

2007-03-11[SCSI] mptsas: Fix oops for insmod during kexecJudith Lebzelter1-2/+5
This fix's an oops during driver load time. mptsas_probe calls mpt_attach(over in mptbase.c). Inside that call, we read some manufacturing config pages to setup some defaults. While reading the config pages, the firmware doesn't complete the reply in time, and we have a timeout. The timeout results in hardreset handler being called. The hardreset handler calls all the fusion upper layer driver reset callback handlers. The mptsas_ioc_reset function is the callback handler in mptsas.c. So where I'm getting to, is mptsas_ioc_reset is getting called before scsi_host_alloc is called, and the pointer ioc->sh is NULL as well as the hostdata.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau4-4/+1
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
