[PATCH] lockdep: annotate DECLARE_WAIT_QUEUE_HEAD

2006-10-30T20:08:40+00:00

kernel: INFO: trying to register non-static key.
kernel: the code is fine but needs lockdep annotation.
kernel: turning off the locking correctness validator.
kernel:  [] show_trace_log_lvl+0x58/0x16a
kernel:  [] show_trace+0xd/0x10
kernel:  [] dump_stack+0x19/0x1b
kernel:  [] __lock_acquire+0xf0/0x90d
kernel:  [] lock_acquire+0x4b/0x6b
kernel:  [] _spin_lock_irqsave+0x22/0x32
kernel:  [] prepare_to_wait+0x17/0x4b
kernel:  [] lpfc_do_work+0xdd/0xcc2 [lpfc]
kernel:  [] kthread+0xc3/0xf2
kernel:  [] kernel_thread_helper+0x5/0xb

Another case of non-static lockdep keys; duplicate the paradigm set by
DECLARE_COMPLETION_ONSTACK and introduce DECLARE_WAIT_QUEUE_HEAD_ONSTACK.

[SCSI] aic79xx: Print out signalling

2006-10-25T22:14:50+00:00

This is a cross-port of a similar patch for aic7xxx;
only it's a bit simpler here as we don't support HVD
and all controller actually implement this register.
I hope.

[SCSI] aic7xxx: Remove slave_destroy

2006-10-25T22:14:46+00:00

This is a cross-port from aic79xx; we still hit the occasional
BUG_ON in slave_destroy. And again we don't really need the
slave_destroy callback nor the ahc_linux_target structure
at all.

[SCSI] aic79xx: set precompensation

2006-10-25T22:14:42+00:00

aic79xx has a special 'iocell' chip which handles the precompensation.
If it's set via DV we should make sure to set the chip correctly, too.

[SCSI] aic79xx: Fixup external device reset

2006-10-25T22:14:38+00:00

Whenever an external device is resetted we really have to take
care to keep the channel in sync. Just notifying SCSI-ML and retry
is not enough as we have to make sure the SCSI bus is not getting
confused, either.
So whenever we detect an external reset we rewrite the command to
TUR, disable packetized command and notify the internal engine
that an abort has happened. This way we trigger a proper bus
reset sequence and all devices will be renegotiated properly.
Kudos to Justin Gibbs and Luben Tuikov for this idea.
