Hi Don,

at should be good to test with for now.

The driver did not load, so I cherry-picked from

git://git.kernel.org/pub/scm/linux/kernel/git/hare/scsi-devel.git
	branch origin/reserved-tags.v6

the following patches:
6a9d1a96ea41 hpsa: move hpsa_hba_inquiry after scsi_add_host()
eeb5cd1fca58 hpsa: use reserved commands
7df7d8382902 hpsa: use scsi_host_busy_iter() to traverse outstanding commands
485881d6d8dc hpsa: drop refcount field from CommandList
c4980ad5e5cb scsi: implement reserved command handling
34d03fa945c0 scsi: add scsi_{get,put}_internal_cmd() helper
4556e50450c8 block: add flag for internal commands
138125f74b25 scsi: hpsa: Lift {BIG_,}IOCTL_Command_struct copy{in,out} into hpsa_ioctl()
cb17c1b69b17 scsi: hpsa: Don't bother with vmalloc for BIG_IOCTL_Command_struct
10100ffd5f65 scsi: hpsa: Get rid of compat_alloc_user_space()
06b43f968db5 scsi: hpsa: hpsa_ioctl(): Tidy up a bit

The driver loads and I ran some mke2fs, mount/umount tests,

ok, great

but I am getting an extra devices in the list which does not
seem to be coming from hpsa driver.

I have not yet had time to diagnose this issue.

I assume that you are missing some other patches from that branch, like these:

77dcb92c31ae scsi: revamp host device handling
6e9884aefe66 scsi: Use dummy inquiry data for the host device
a381637f8a6e scsi: use real inquiry data when initialising devices

@Hannes, Any plans to get this series going again?

Thanks,
John
