* | [SCSI] modify change_queue_depth to take in reason why it is being calledMike Christie2009-12-041-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies scsi_host_template->change_queue_depth so that it takes an argument indicating why it is being called. This will be used so that if a LLD needs to do some extra processing when handling queue fulls or later ramp ups, it can do so. This is a simple port of the drivers setting a change_queue_depth callback. In the patch I just have these LLDs adjust the queue depth if the user was requesting it.

| | | | | | | | | | | | | | As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

| | | | | | | | | | | | | Right now SCSI and others do their own command timeout handling. Move those bits to the block layer.

| | | | | | | | | | | | | | | | | | | Newer Dell CERC firmware (>= 6.62) implement a random deletion handling compatible with the legacy megaraid driver. The legacy handling shifted the target ID by 0x80 only for I/O commands (READ/WRITE/etc), whereas megaraid_mbox shifts the target ID always if random deletion is supported. The resulted in megaraid_mbox sending an INQUIRY to the wrong channel, and not finding any devices, obviously. So we disable the random deletion support if the offending firmware is found.

* [SCSI] MegaRAID driver management char device moved to miscThomas Horsten2008-02-112-7/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | The MegaRAID driver's common management module (megaraid_mm.c) creates a char device used by the management tool "megarc" from LSI Logic (and possibly other management tools). In 2.6 with udev, this device doesn't get created because it is not registered in sysfs. I first fixed this by registering a class "megaraid_mm", but realized that this should probably be moved to misc devices, instead of taking up a char major. This is because only 1 device is used, even if there are multiple adapters - the minor is never used (the adapter info is in the ioctl block sent to the driver, not detected based on the minor number as one might think). So it is a complete waste to have an entire major taken by this. So it now uses a misc device which I named "megadev0" (the name that megarc expects), and has a dynamic minor (previoulsy a dynamic major was used). I have tested this on my own system with the megarc tool, and it works just as fine as before (only now the device gets created correctly by udev).
