* [PATCH] Driver Core: fix up all callers of class_device_create()Greg Kroah-Hartman2005-10-28
| | | | | | | | The previous patch adding the ability to nest struct class_device changed the paramaters to the call class_device_create(). This patch fixes up all in-kernel users of the function. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] Driver core: pass interface to class interface methodsDmitry Torokhov2005-10-28
| | | | | | | | | | | Driver core: pass interface to class intreface methods Pass interface as argument to add() and remove() class interface methods. This way a subsystem can implement generic add/remove handlers and then call interface-specific ones. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] qlogic lockup fixAndrew Morton2005-10-25
| | | | | | | | | | | | | | | If qla2x00_probe_one()'s call to qla2x00_iospace_config() fails, we call qla2x00_free_device() to clean up. But because ha->dpc_pid hasn't been set yet, qla2x00_free_device() tries to stop a kernel thread which hasn't started yet. It does wait_for_completion() against an uninitialised completion struct and the kernel hangs up. Fix it by initialising ha->dpc_pid a bit earlier.

| * [SCSI] Fix leak of Scsi_CmndsAlan Stern2005-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | When a request is deferred in scsi_init_io because the sg table could not be allocated, the associated scsi_cmnd is not released and the request is not marked with REQ_DONTPREP. When the command is retried, if scsi_prep_fn decides to kill it then the scsi_cmnd will never be released. This patch (as573) changes scsi_init_io so that it calls scsi_put_command before deferring a request.

| * [SCSI] Fix aacraid regressionSalyzyn, Mark2005-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Juan was kind enough to linger on site, and work on a production machine, to try the parameter to make the system stable. He discovered that reducing the maximum transfer size issued to the adapter to 128KB stabilized his system. This is related to an earlier change for the 2.6.13 tree resulting from Martin Drab's testing where the transfer size was reduced from 4G to 256KB; we needed to go still further in scaling back the request size. Here is the patch that tames this regression. Signed-off-by: Mark Salyzyn <aacraid@adaptec.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [SCSI] Legacy MegaRAID: Fix READ CAPACITYJames Bottomley2005-10-03
| | | | | | | | | | | | | | | | | | | | | | Some Legacy megaraid cards can't actually cope with the scatter/gather version of the READ CAPACITY command (which is what we now send them since altering all SCSI internal I/O to go via the block layer). Fix this (and a few other broken megaraid driver assumptions) by sending the non-sg version of the command if the sg list only has a single element.

| * [SCSI] aic7xxx/aic79xx: fix module removal path not to panicJames Bottomley2005-10-02
| | | | | | | | | | | | | | | | | | | | | | | | In these drivers, scsi_remove_host() is called too late, at the point it is called, the driver has already shut down too far to accept any I/O that the shutdown might generate. Any generated I/O actually triggers a panic. Fix this by calling scsi_remove_host() as early as possible and not calling scsi_host_put() until just before we kfree the ahc_softc.

| * [SCSI] fix potential panic with proc on module removalJames Bottomley2005-10-02
| | | | | | | | | | | | | | | | | | | | | | | | There's a problem in our host release in that it calls scsi_proc_hostdir_rm(). However, if you hold a reference to the host as you remove the module, the host template (which proc uses) will be freed and the system will panic when the host device is finally released. Fix this by moving scsi_proc_hostdir_rm() to where it should be: in scsi_remove_host(). Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| * [SCSI] aacraid: remove aac_insert_entryMark Haverkamp2005-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn from Adaptec. High Priority Queues have *never* been used in the entire history of the aac based adapters. Associated with this, aac_insert_entry can be removed, SavedIrql can be removed & padding variable can be removed. With the movement of SavedIrql out & replaced with an automatic variable qflags, the locking can be refined somewhat. The sparse warnings did not catch the need for byte swapping in the 'dprintk' debugging print macros, so fixed this up when this code was moved outside of the now refined locking.

| * [SCSI] aacraid: fib size math fixMark Haverkamp2005-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn from Adaptec. The size of the command packet's scatter gather list maximum size was miscalculated in the low range leading to the driver initialization limiting the maximum i/o size that could go to the Adapter. There were no negative operational side effects resulting from this bad math, only a subtle limit in performance of the Adapter at the top end of the range.

| * [SCSI] aacraid: initialization timeoutMark Haverkamp2005-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn from Adaptec. In the rare instances where the adapter, or the motherboard, is misbehaving; driver initialization or shutdown becomes problematic. By introducing a 3 minute timeout on the first interrupt driven command during initialization, or the issuance of the adapter shutdown command during driver unload, we can resolve the lockup problems induced by common (but rare) hardware misbehaviors. The timeout during initialization, should it occur, is accompanied by a message presented to the console and the logs indicating that the user should inspect and resolve problems with interrupt routing.

There are a few adapters that are capable of creating devices with this large of a capacity, but now that we have the large fib support in, the management applications will be capable of generating them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as545) fixes the list traversals in __scsi_remove_target and scsi_forget_host. In each case the existing code list_for_each_entry_safe in an _unsafe_ manner, because the list was not protected from outside modification while the iteration was running. The new scsi_forget_host routine takes the moderately controversial step of iterating over devices for removal rather than iterating over targets. This makes more sense to me because the current scheme treats targets as second-class citizens, created and removed on demand, rather than as objects corresponding to actual hardware. (Also I couldn't figure out any safe way to iterate over the target list, since it's not so easy to tell when a target has already been removed.)

I was going to do this eventually, honest, because there's no need to unprep and reprep a command that comes in through scsi_queue_insert(). However, I decided to leave it in to exercise the scsi_unprep_request() path just to make sure it was working. What's happening, I think, is that we also use this path for retries. Since we kill and reget the command each time, the retries decrement is never seen, so we're retrying forever. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
