- Replace scsi_device_types array API with scsi_device_type function API. Gets rid of a lot of common code, as well as being easier to use. - Add the new device types in SPC4 r05a, and rename some of the older ones. - Reformat the printing of inquiry data; now fits on one line and includes PQ. I think I've addressed all the feedback from the previous versions. My current test box prints: scsi 2:0:1:0: Direct access HP 18.2G ATLAS10K3_18_SCA HP05 PQ: 0 ANSI: 2 Signed-off-by: NMatthew Wilcox <matthew@wil.cx> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

Currently struct scsi_cmnd has various fields that are used to backup original data after the corresponding fields have been overridden for EH commands. This means drivers can easily get at it and misuse it. Due to the old_ naming this doesn't happen for most of them, but two that have different names have been used wrong a lot (see previous patch). Another downside is that they unessecarily bloat the scsi_cmnd size. This patch moves them onstack in scsi_send_eh_cmnd to fix those two issues aswell as allowing future EH fixes like moving the EH command submissions to use SG lists like everything else.

由 Luben Tuikov 提交于
Introduce scsi_req_abort_cmd(struct scsi_cmnd *). This function requests that SCSI Core start recovery for the command by deleting the timer and adding the command to the eh queue. It can be called by either LLDDs or SCSI Core. LLDDs who implement their own error recovery MAY ignore the timeout event if they generated scsi_req_abort_cmd.

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: NJames Bottomley <James.Bottomley@SteelEye.com>

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.

As devfs has been disabled from the kernel tree for a number of months now (5 to be exact), here's a patch against 2.6.16-rc1-git1 that removes support for it from the SCSI subsystem.

percpu_data blindly allocates bootmem memory to store NR_CPUS instances of cpudata, instead of allocating memory only for possible cpus. As a preparation for changing that, we need to convert various 0 -> NR_CPUS loops to use for_each_cpu(). (The above only applies to users of asm-generic/percpu.h. powerpc has gone it alone and is presently only allocating memory for present CPUs, so it's currently corrupting memory).

There are certain rogue devices (and the aic7xxx driver) that return BUSY or QUEUE_FULL forever. This code will apply a global timeout (of the total number of retries times the per command timer) to a given command. If it is exceeded, the command is completed regardless of its state. The patch also removes the unused field in the command: timeout and timeout_total. This solves the problem of detecting an endless loop in the mid-layer because of BUSY/QUEUE_FULL bouncing, but will not recover the device. In the aic7xxx case, the driver can be recovered by sending a bus reset, so possibly this should be tied into the error handler? Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

scsi_queue_insert() has four callers. Three callers call with timer disabled and one (the second invocation in scsi_dispatch_cmd()) calls with timer activated. scsi_queue_insert() used to always call scsi_delete_timer() and ignore the return value. This results in race with timer expiration. Remove scsi_delete_timer() call from scsi_queue_insert() and make the caller delete timer and check the return value.

scsi_dispatch_cmd currently calls scsi_done when the device is in the SDEV_DEL state, but at this point the command has not had a timer added to it (this is done a couple lines down) so scsi_done just returns and the command is lost. The attached patch made against 2.6.12-rc3 calls __scsi_done in this case so the comamnd will be returned upwards.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
