Supported events include LIP, LIP reset, RSCN, link up, and link down. To support AEN (and additional forthcoming features), we also introduce a simple deferred-work construct to manage events which require a non-atomic sleeping-capable context. This work-list is processed as part of the driver's standard DPC routine. Signed-off-by:

There's no need to use the heavier (albiet safer) *_irq[save|restore]() locking primitives within the driver's interrupt handlers, interrupts are guaranteed to be non-reentrant. Use lightweight spin_lock() and spin_unlock() primitives while acquiring the hardware_lock. Signed-off-by:

These are completely wrong because both outX and writeX do an automatic reverse of their arguments if necessary, so having an extra cpu_to_leX gives us the wrong ordering on BE platforms again. Acked-by:

Two functions in include/scsi/sas_ata.h don't have static inlines leading to problems if they're built in: On Thu, 2008-04-03 at 14:06 +0200, Toralf Förster wrote: > drivers/scsi/mvsas.o: In function `sas_ata_init_host_and_port': > mvsas.c:(.text+0x0): multiple definition of `sas_ata_init_host_and_port' > drivers/scsi/libsas/built-in.o:(.text+0x37f4): first defined here > drivers/scsi/mvsas.o: In function `sas_ata_task_abort': > mvsas.c:(.text+0x7): multiple definition of `sas_ata_task_abort' > drivers/scsi/libsas/built-in.o:(.text+0x37fb): first defined here > make[2]: *** [drivers/scsi/built-in.o] Error 1 > make[1]: *** [drivers/scsi] Error 2 > make: *** [drivers] Error 2 Add the correct static inline modifiers.

Every current transport class calls transport_container_release but ignores the return value. This is catastrophic if it returns an error because the containers are part of a global list and the next action of almost every transport class is to free the memory used by the container. Fix this by making transport_container_release a void, but making it BUG if attribute_container_release returns an error ... this catches the root cause of a system panic much earlier. If we don't do this, we get an eventual BUG when the attribute container list notices the corruption caused by the freed memory it's still referencing. Also made attribute_container_release __must_check as a reminder. Cc: Greg KH <greg@kroah.com> Signed-off-by: -

Currently, if the barrier command fails, the error return isn't seen by the block layer and it proceeds on regardless. The problem is that SCSI always returns no error for REQ_TYPE_BLOCK_PC ... it expects the submitter to pick the errors out of req->errors, which the block barrier functions don't do. Since it appears that the way SG_IO and scsi_execute_request() work they discard the block error return and always use req->errors, the best fix for this is to have the SCSI layer return an error to block if one actually occurred (this also allows us to filter out spurious errors, like deferred sense). This patch is a bug fix that will need backporting to stable, but it's also quite a big change and in need of testing, so we'll incubate in the main kernel tree and backport at the -rc2 or so stage if no problems turn up.

This patch adds per request hardware debugging data to the trace record which is written per request. It's a replacement for some sad kernel message based debugging code. Considering the amount of trace data, printk() is not suitable for this stuff. Writing binary traces is more efficient. In addition we got all information in one place. The QTCB trace data is only dumped for requests other than SCSI requests. Otherwise we would flood the trace ring buffer. We are mostly interested in non-SCSI, recovery related requests here anyway. This patch also works around a known hardware bug. It truncates QTCB traces so that we do not save unused areas of the hardware trace. Signed-off-by:
