* Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-05-21[SCSI] qla2xxx: Conditionally disable automatic queue full tracking.Michael Reed3-0/+19
Changing a lun's queue depth (/sys/block/sdX/device/queue_depth) isn't sticky when the device is connected via a QLogic fibre channel adapter. The QLogic qla2xxx fibre channel driver dynamically adjusts a lun's queue depth. If a user has a specific need to limit the number of commands issued to a lun (say a tape drive, or a shared raid where the total commands issued to all luns is limited at the controller level, for example) and writes a limiting value to /sys/block/sdXX/device/queue_depth, the qla2xxx driver will silently and gradually increase the queue depth back to the driver limit of ql2xmaxqdepth. While reducing this value (module parameter) or increasing the interval between ramp ups (ql2xqfullrampup) offers the potential for a work around it would be better to have the option of just disabling the dynamic adjustment of queue depth. This patch implements an "off switch" as a module parameter.

Set the module parameter ql2xmultique_tag to 1 to enable this feature. In this mode, the total number of response queues created is equal to the number of online cpus. Turning the block layer's rq_affinity mode on enables requests to be routed to the proper cpu and at the same time it enables completion of the IO in a response queue that is affined to the cpu in the request path.

The short-circuit to skip the non-applicable 'full-login-lip' process on 81xx ISPs was nested too deeply in the 'bus-reset' routine, as the code in qla2x00_loop_reset() should skip the whole enable_lip_full_login process. The original code could cause device tear-down due to the qla2x00_wait_for_loop_ready() call taking a large amount of time.
