In the highly unusual case where two threads are running concurrently through
the scanning code scanning the same target, we run into the situation where
one may allocate the target while the other is still using it. In this case,

This patch eliminates the reap_ref and replaces it with a proper kref.
On last put of this kref, the target is removed from visibility in
sysfs. The final call to scsi_target_reap() for the device is done from
__scsi_remove_device() and only if the device was made visible. This
ensures that the t
This set should fix our target problems with USB by making the target
visibility properly reference counted. Since it's a major change to the
infrastructure, we'll incubate upstream first before backporting to
stable.

This patch adds support for the APM X-Gene SoC SATA host controller driver.
It requires the corresponding APM X-Gene SoC PHY driver.

This patch adds support for the APM X-Gene SoC SATA host controller. In
order for the host controller to work, the corresponding PHY driver
musts also be available.

In SAS systems, it's common for controllers and expanders to rotate spinup
permission across phys to avoid overloading the power supply (e.g., if the
system is sized to support 8 x 18 W drives, it might not work if 8 x 45 W
are briefly consumed). The most common algorithm allows n phys to spinup

Hi,
This patch implements support for inhibiting setting LUN number
for SCSI custom command send via /dev/sgX with ioctl(.., SG_IO, ...) call.
This solves problems with some devices which claim support of
SCSI v1/v2, but for some special purposes use custom commands
which does not conform with st

Hello, Hannes

The functions sleep_on, sleep_on_timeout, interruptible_sleep_on

sleep_on is known broken and going away. The atari_scsi driver is one of
two remaining users in the falcon_get_lock() function, which is a rather
crazy piece of code. This does not attempt to fix the driver's locking
scheme in general, but at least prevents falcon_get_lock from going to
sleep when
