cciss: reinstate proper FIFO order of command queue list

2011-01-10T20:50:33+00:00

Commit 8a3173de inadvertently changed the ordering when
switching to hlists. Change to regular list heads so we
can use tail list adds, this improves performance.

cciss: fix cciss_revalidate panic

2010-12-17T08:01:37+00:00

If you delete a logical drive, and then run BLKRRPART (e.g. via fdisk)
on a logical drive which is "after" the deleted logical drive in the h->drv[]
array, then cciss_revalidate panics because it will access the null pointer
h->drv[x] when x hits the deleted drive.

cciss: fix build for PROC_FS disabled

2010-11-17T10:56:13+00:00

The recent patch to fix the removal of a non-existing proc
directory introduced this build problem for !CONFIG_PROC_FS:

drivers/block/cciss.c:4929: error: 'proc_cciss' undeclared (first use in this function)

Fix it by moving proc_cciss outside of the CONFIG_PROC_FS scope.

cciss: fix proc warning on attempt to remove non-existant directory

2010-11-10T13:40:52+00:00

Randy reports that he gets the following stack trace when
removing the cciss module:

which will happen if you don't actually have an HP CISS adapter,
since it'll do an uncondional removal of a proc directory it
never attempted to create in that case.

cciss: remove overlapping PCI IDs

2010-10-28T12:33:27+00:00

This patch removes the controller overlap between cciss and hpsa. It was
decided that no overlap should exist. All new controllers will use the hpsa
SCSI based driver.

block: cciss: fix information leak to userland

2010-10-28T12:31:55+00:00

Structure IOCTL_Command_struct is copied to userland with
some padding fields at the end of the struct unitialized.
It leads to leaking of contents of kernel stack memory.
