As James B. correctly noted, ahd_reset_channel() in ahd_linux_bus_reset() should be protected by ahd_lock(). However, the main reason for not doing so was a deadlock with the interesting polling mechanism to detect the end a bus reset. This patch replaces the polling mechanism with a saner signalling via flags; it also gives us the benefit of detecting any multiple calls to ahd_reset_channel(). Signed-off-by:

Original From: Ingo Flaschberger <if@xip.at> To support the RA4100 array from Compaq. This patch now correctly handles SCSI_UNKNOWN types with regard to BLIST_REPORTLUNS2 (allow it) and cdb[1] LUN inclusion (don't). It also allows a BLIST_MAX_512 flag to restrict the maximum transfer length to 512 blocks (apparently this is an RA4100 problem). Signed-off-by: -

When spinlock debugging is turned on, a struct completion grows beyond the size allowed for the scsi_pointer. So move the struct completion back onto the stack. The additional memory barriers are to keep us from completing a random piece of kernel stack if the command happens to complete after the error handling has finished. Signed-off-by:

Fixup a check used by the ipr driver to determine if a given device is a SCSI disk. Due to the addition of support for attaching SATA devices, this check needs to be more robust. Signed-off-by:

Instead of NULLing the resource entry pointer when a disk goes away to prevent any new commands being sent to it, set the adapter resource handle to an invalid value so new ops getting sent to it will fail with a selection timeout response. This patch is needed for future SATA patches. Signed-off-by:

when the sg driver is unable to setup direct IO, free that scatter gather list prior to falling back to indirect IO Further to this thread started by Bryan Holty: http://marc.theaimsgroup.com/?l=linux-scsi&m=114306885116728&w=2 Here is the reworked patch again. This time it has been tested with a program provided by Bryan. Signed-off-by:

for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future. This patch replaces for_each_cpu with for_each_possible_cpu. Signed-off-by:

This patch enables clustering and sets max_sectors to 0xffff to enable reading and writing of large blocks with tapes (and large transfers with sg). This change is needed after the sg and st drivers started using chained bios through scsi_request_async() in 2.6.16. Signed-off-by:

Use wait_for_completion_timeout() instead of using a timer (as Christoph Hellwig did for aic7xxx). That lets me eliminate the sym_eh_wait structure; the struct completion, the old_done pointer and the to_do flag can be folded into the sym_ucmd (which overrides the scsi_pointer in scsi_cmnd). The sym_eh_done() function becomes much simpler as the timeout handling is done in sym_eh_handler() directly. The host_lock can be unlocked earlier, and I cache the host in a local variable to make accesses to it quicker. Signed-off-by:

Undef SYM_OPT_HANDLE_DEVICE_QUEUEING. Call sym_put_start_queue instead of sym_start_next_ccbs. Turn asserts into checks that we can send the command to the adapter, and return busy from queuecommand if we can't. Signed-off-by:

Most of the Kconfig options for switching between IO Port and MMIO operations use the opposite sense from sym2. Really, this option should be set at a chipset level rather than per-driver. Signed-off-by:

There is a window where we can be re-enabling an adapter, but still allow SCSI commands to be sent to the target. This fix sets our window (request_limit) to -1 as soon as we know the adapter is being reenabled, and closes a very teeny tiny window where we could set the window back to 1 before we grab a lock.

We currently have two implementations of this obsolete ioctl, one in the block layer and one in the scsi code. Both of them have drawbacks. This patch kills the scsi layer version after updating the block version with the missing bits: - argument checking - use scatterlist I/O - set number of retries based on the submitted command This is the last user of non-S/G I/O except for the gdth driver, so getting this in ASAP and through the scsi tree would be nie to kill the non-S/G I/O path. Jens, what do you think about adding a check for non-S/G I/O in the midlayer? Thanks to Or Gerlitz for testing this patch. Signed-off-by:
