* [SCSI] for_each_possible_cpu: scsiKAMEZAWA Hiroyuki2006-04-13
| | | | | | | | | | | | | | | | 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.

* [SCSI] Remove devfs support from the SCSI subsystemGreg KH2006-02-27
| | | | | | | | | | | | 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. The patch also removes the scsi_disk devfs_name field as it's no longer needed. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [PATCH] percpu data: only iterate over possible CPUsEric Dumazet2006-02-05
| | | | | | | | | | | | | | | | | | | | | | | 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).

* [PATCH] Fix a bug in scsi_get_commandMatthew Dobson2005-11-22
| | | | | | | | | | | scsi_get_command() attempts to write into a structure that may not have been successfully allocated. Move this write inside the if statement that ensures we won't panic the kernel with a NULL pointer dereference.

* [SCSI] move the mid-layer printk's over to shost/starget/sdev_printkJames Bottomley2005-10-28
| | | | | | | | | This should eliminate (at least in the mid layer) to make numeric assumptions about any of the enumeration variables. As a side effect, it will also make all the messages consistent and line us up nicely for the error logging strategy (if it ever shows itself again).

* [SCSI] fix oops on usb storage device disconnectJames Bottomley2005-09-19
| | | | | | | | | We fix the oops by enforcing the host state model. There have also been two extra states added: SHOST_CANCEL_RECOVERY and SHOST_DEL_RECOVERY so we can take the model through host removal while the recovery thread is active.

* [SCSI] add global timeout to the scsi mid-layerJames Bottomley2005-08-08
| | | | | | | | | | | | | | | | | | 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: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] remove scsi_cmnd->stateChristoph Hellwig2005-06-26
| | | | | | | | | We never look at it except for the old megaraid driver that abuses it for sending internal commands.

| * [SCSI] call correct scsi_done function in scsi_dispatch_cmdMike Christie2005-05-01
| | | | | | | | | | | | | | | | | | | | | | 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.

* | [SCSI] remove a timer race in scsi_queue_insert()Tejun Heo2005-05-20
|/ | | | | | | | | | | | | | 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.

* [PATCH] scsi: remove meaningless scsi_cmnd->serial_number_at_timeout field2005-04-18
| | | | | | | | | | | | | scsi_cmnd->serial_number_at_timeout doesn't serve any purpose anymore. All serial_number == serial_number_at_timeout tests are always true in abort callbacks. Kill the field. Also, as ->pid always equals ->serial_number and ->serial_number doesn't have any special meaning anymore, update comments above ->serial_number accordingly. Once we remove all uses of this field from all lldd's, this field should go. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
