bcache: Use bd_link_disk_holder()
bcache: Allocator cleanup/fixes
cciss: bug fix to prevent cciss from loading in kdump crash kernel
cciss: add cciss_allow_hpsa module parameter
drivers/block/mg_disk.c: add CONFIG_PM_SLEEP to suspend/resume functions

This patch adds a new debugfs entry 'device_status' in
/sys/kernel/debug/rssd. The value of this entry shows
devices online and those in the process of removing.

Hi Jens,
Another tiny patch.

On module load, creates a debugfs parent 'rssd' in debugfs root. Then for each
device, create a new node with corresponding disk name. Under the new node, two
entries 'registers' and 'flags' are created.
NOTE: These entries were removed from sysfs in the previous patch

* If a ncq command time out and a non-ncq command is active, skip restart port
* Queue(pause) ncq commands during operations spanning more than one non-ncq commands - secure erase, download microcode
* When a non-ncq command is active, allow incoming non-ncq commands to wait instead of failing back
* Changed timeout for download microcode and smart commands
* If the device in write protect mode, fail all writes (do not send to device)
* Set maximum retries to 2
