cciss: fix memory leak

2007-07-31T22:39:43+00:00

There's a memory leak in the cciss driver.

in alloc_cciss_hba() we may leak sizeof(ctlr_info_t) bytes if a
call to alloc_disk(1 << NWD_SHIFT) fails.
This patch should fix the issue.

Spotted by the Coverity checker.

[BLOCK] Get rid of request_queue_t typedef

2007-07-24T07:28:11+00:00

Some of the code has been gradually transitioned to using the proper
struct request_queue, but there's lots left. So do a full sweet of
the kernel and get rid of this typedef and replace its uses with
the proper type.

cciss: Fix pci_driver.shutdown while device is still active

2007-05-19T04:03:49+00:00

Fix an Oops in the cciss driver caused by system shutdown while a filesystem
on a cciss device is still active.  The cciss_remove_one function only
properly removes the device if the device has been cleanly released by its
users, which is not the case when the pci_driver.shutdown method is called.

This patch adds a new cciss_shutdown function to better match the pattern
used by various SCSI drivers: deactivate device interrupts and flush caches.
It also alters the cciss_remove_one function to match and readds the
__devexit annotation that was removed when cciss_remove_one was serving as
the pci_driver.shutdown method.

cciss: include scsi/scsi.h unconditionally

2007-05-08T18:15:10+00:00

Make cciss unconditionally include scsi/scsi.h, because of the use of
SCSI_IOCTL_GET_IDLUN and SCSI_IOCTL_GET_BUS_NUMBER.

cciss: set rq->errors more correctly in driver

2007-05-08T18:15:09+00:00

Set rq->errors more correctly in cciss driver.  Previously we had set it
synonymously with the meaning of the last parameter of end_that_last_request
and complete_buffers (the "uptodate" parameter) and had gotten away with it
for all this time because nobody ever looked at rq->errors.
SCSI_IOCTL_SEND_COMMAND looks at rq->errors, so now it matters that it be
right.

cciss: add SG_IO ioctl to cciss

2007-05-08T18:15:09+00:00

For all of you that think cciss should be a scsi driver here is the patch that
you have been waiting for all these years. This patch actually adds the SG_IO
ioctl to cciss. The primary purpose is for clustering and high-availibilty.
But now anyone can exploit this ioctl in any manner they wish.

Note, SCSI_IOCTL_SEND_COMMAND doesn't work with this patch due to rq->errors
being set incorrectly.  Subsequent patch fixes that.
