| * [SCSI] qla2xxx: Drop use of IRQF_DISABLE.Giridhar Malavali2009-04-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When IRQs are shared by multiple controllers and if the first one to register does not disable the IRQ, then IRQ will be enabled for all other controllers by default, irrespective of their setting. With IRQF_DISABLED registration, the driver interrupt routine was called with interrupt enabled always. Disbaling the registration with IRQF_DISABLED, since driver code is re-entrant safe and all critical sections are guarded with interrupt safe locks.

| | | | | | | | | | | | | | | | | | | | | | | | | | Given the low-level interface varies from one flash-part manufacturer to the next, the Flash-Access-Control (FAC) mailbox command makes the specific flash type transparent to the driver by encapsulating a basic set of accessor and update routines.

| | | | | | | | | | | | | | | | | | | | | | | | The ibmvfc driver currently breaks the CRQ and essentially resets the entire virtual FC adapter, killing all outstanding ops to all attached targets, if an ADISC times out during target discover/rediscovery. This patch adds some code to cancel the ADISC if it times out, which prevents a single ADISC timeout from affecting the other devices attached to the fabric.

| | | | | | | | | | | | | | | | | | | | The ibmvfc driver really does not handle dynamically changing disc_threads.

| * [SCSI] ibmvfc: Fix dropped interruptsBrian King2009-04-032-2/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a problem of possible dropped interrupts. Currently, the ibmvfc driver has a race condition where after ibmvfc_interrupt gets run, the platform code clears the interrupt. This can result in lost interrupts and, in worst case scenarios, result in command timeouts. Fix this by implementing a tasklet similar to what the ibmvscsi driver does so that interrupt processing is no longer done in the actual interrupt handler, which eliminates the race.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ch module is missing the scsi:t-0x08* alias that would cause it to be auto-loaded when a device of that type if found by udev, requiring udev to have a specific rule just for this one module. This patch adds the alias. Signed-off-by: Scott James Remnant <scott@canonical.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

We actually do not need to access the curr task in this path, because if it is a cmd task the fail_command call will handle this and if it is mgmt task then the flush of the mgmt queues will handle that.

| * | | | | [SCSI] iscsi class: remove host no argument from session creation calloutMike Christie2009-03-133-10/+6Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We do not need to have llds set the host no for the session's parent, because we know the session's parent is going to be the host. This removes it from the session creation callback and converts the drivers. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
| * | | | | [SCSI] libiscsi: pass session failure a session structMike Christie2009-03-131-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The api for conn and session failures is akward because one takes a conn from the lib and one takes a session from the class. This syncs up the interfaces to use structs from the lib. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
| * | | | | [SCSI] iscsi lib: remove qdepth param from iscsi host allocationMike Christie2009-03-133-11/+8Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The qdepth setting was useful when we needed libiscsi to verify the setting. Now we just need to make sure if older tools passed in zero then we need to set some default. So this patch just has us use the sht->cmd_per_lun or if for LLD does a host per session then we can set it on per host basis.
