The following changes since commit 41e9a69641fb3fa86fa9277a179f3ad261d072f7:
[SCSI] ipr: Stop reading adapter dump prematurely (2011-09-22 15:30:28 +0400)
are available in the git repository at:
git://github.com:djbw/linux.git libsas
These have all appeared on the mailing list previously save for the last
one "libsas: remove unused ata_task_resp fields" (just a cleanup).
Just a convenience branch since isci's atapi support needed the lun
scanning fixup as a baseline.
Dan Williams (7):
libsas: disable scanning lun > 0 on ata devices
libsas: fix ->change_queue_{depth|type} for sata devices
libsas: dynamic queue depth
mvsas: remove mvs_slave_{alloc|configure}
pm8001: remove pm8001_slave_{alloc|configure}
libsas: fix try_test_sas_gpio_gp_bit() build error

libsas: remove unused ata_task_resp fields
Commit 1e34c838 "libsas: remove spurious sata control register read/write"
removed the routines to retrieve the sata control register, now remove the
unused data structure fields to remove any remaining confusion.

libsas: fix try_test_sas_gpio_gp_bit() build error
If the user has disabled CONFIG_SCSI_SAS_HOST_SMP then libsas drivers
will not be receiving smp-gpio frames and do not need this lookup code.

pm8001: remove pm8001_slave_{alloc|configure}
libsas handles:
1/ limiting ata scanning to lun0
2/ changes to /sys/block/<sdX>/device/queue_depth for ata devices
libata handles turning off ncq globally via kernel command line
(libata.force=noncq) or sysfs (echo 1 >
/sys/block/<sdX>/device/queue_depth). A lldd specific compile option is
not necessary.

libsas: dynamic queue depth
The queue-depth for libsas-attached devices initializes to 32 and can
only be increased manually via sysfs to a max of 64, while mpt2sas
attached devices initialize to 254 and dynamically float via the
midlayer ->change_queue_depth interface.
No performance regression was observed with this change on the isci
driver.

libsas: fix ->change_queue_{depth|type} for sata devices
Pass queue_depth change requests to libata, and prevent queue_type
changes for ATA devices.
Otherwise:
1/ we do not honor the libata specific restrictions on the queue depth
2/ libsas drivers that do not set sdev->tagged_supported are unable to
change the queue_depth of ata devices via sysfs

libsas: disable scanning lun > 0 on ata devices
Currently mvsas and pm8001 have custom ->slave_alloc implementations to
achieve this. Uplevel it for all libsas drivers as isci encounters problems
with atapi devices when scanning past lun0.
Just do what Darrick suggested [1], and limit the scan for ata devices.

Given that none of the patches on the libsas-fixes branch would pass
Linus' "does this fix a known regression" test for late rc changes I
have gone ahead and moved those patches over to the libsas branch. No
other changes have been made.
The locking fix might be a consideration, but since it has been this
way for quite a few releases we can wait for the 3.2 merge and submit
it to -stable.
