| | | | | | | | | | | | | | | | | | | | | | This patch fix for sata IO circular lock dependency. When we call task_done for SATA IO, we have got pm8001_ha->lock ,and in sas_ata_task_done, it will get (dev->sata_dev.ap->lock. then cause circular lock dependency .So we should drop pm8001_ha->lock when we call task_done for SATA task.

| * [SCSI] ipr: fix EEH recoveryKleber Sacilotto de Souza2009-12-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After commits c82f63e411f1b58427c103bd95af2863b1c96dd1 (PCI: check saved state before restore) and 4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff (PCI: Clear saved_state after the state has been restored) PCI drivers are prevented from restoring the device standard configuration registers twice in a row. These changes introduced a regression on ipr EEH recovery. The ipr device driver saves the PCI state only during the device probe and restores it on ipr_reset_restore_cfg_space() during IOA resets. This behavior is causing the EEH recovery to fail after the second error detected, since the registers are not being restored. One possible solution would be saving the registers after restoring them. The problem with this approach is that while recovering from an EEH error if pci_save_state() results in an EEH error, the adapter/slot will be reset, and end up back in ipr_reset_restore_cfg_space(), but it won't have a valid saved state to restore, so pci_restore_state() will fail. The following patch introduces a workaround for this problem, hacking around the PCI API by setting pdev->state_saved = true before we do the restore. It fixes the EEH regression and prevents that we hit another EEH error during EEH recovery. [jejb: fix is a hack ...

| * [SCSI] libosd: Fix blk_put_request locking againBoaz Harrosh2009-12-101-41/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So libosd has decided to sacrifice some code simplicity for the sake of a clean API. One of these things is the possibility for users to call osd_end_request, in any condition at any state. This opens up some problems with calling blk_put_request when out-side of the completion callback but calling __blk_put_request when detecting a from-completion state. The current hack was working just fine until exofs decided to operate on all devices in parallel and wait for the sum of the requests, before deallocating all osd-requests at once. There are two new possible cases 1. All request in a group are deallocated as part of the last request's async-done, request_queue is locked. 2. All request in a group where executed asynchronously, but de-allocation was delayed to after the async-done, in the context of another thread. Async execution but request_queue is not locked. The solution I chose was to separate the deallocation of the osd_request which has the information users need, from the deallocation of the internal(2) requests which impose the locking problem. The internal block-requests are freed unconditionally inside the async-done-callback, when we know the queue is always locked. If at osd_end_request time we still have a bock-request, then we know it did not come from within an async-done-callback and we can call the regular blk_put_request. The internal requests were used for carrying error information after execution. This information is now copied to osd_request members for later analysis by user code. The external API and behaviour was unchanged, except now it really supports what was previously advertised.

| * [SCSI] megaraid_sas: make driver PCI legacy I/O port free driverNoriyuki Fujii2009-12-101-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the large servers, I/O port resource may not be assigned to all the PCI devices since it is limited (to 64KB on Intel Architecture[1]) and it may also be fragmented (I/O base register of PCI-to-PCI bridge will usually be aligned to a 4KB boundary[2]). If no I/O port resource is assigned to devices, those devices do not work. [1] Some machines support 64KB I/O port space per PCI segment. [2] Some P2P bridges support optional 1KB aligned I/O base. Therefore, I made a patch for MegaRAID SAS driver to make PCI legacy I/O port free. I have also tested the patch and it had no problem. The way to make PCI legacy I/O port free is the same as Fusion-MPT driver's and it has been merged into 2.6.30.4. This has already been fixed in e1000 and lpfc. As a result of the above, the driver can handle its device even when there are a huge number of PCI devices being used on the system and no I/O port region assigned to the device.

| * [SCSI] st: fix mdata->page_order handlingFUJITA Tomonori2009-12-102-11/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dio transfer always resets mdata->page_order to zero. It breaks high-order pages previously allocated for non-dio transfer. This patches adds reserved_page_order to st_buffer structure to save page order for non-dio transfer. http://bugzilla.kernel.org/show_bug.cgi?id=14563 When enlarge_buffer() allocates 524288 from 0, st uses six-order page allocation. So mdata->page_order is 6 and frp_seg is 2. After that, if st uses dio, sgl_map_user_pages() sets mdata->page_order to 0 for st_do_scsi(). After that, when we call normalize_buffer(), it frees only free frp_seg * PAGE_SIZE (2 * 4096) though we should free frp_seg * PAGE_SIZE << 6 (2 * 4096 << 6). So we see buffer_size is set to 516096 (524288 - 8192).

| | | | | | | | | | | | | | | | | | | | | | | | | | If transport_class_register fails we should unregister any registered classes, or we will leak memory or other resources. I did a quick modprobe of scsi_transport_fc to test the patch.

| | | | | | | | | | | | | | | | | | | | | | In testing 2.6.31 on one of our ia64 platforms I've encountered a hang due to the driver using hardware ATEs which are a limited resource. This is because the driver does not set the dma consistent mask to 64 bits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently, We marked strstrip() as must_check. because it was frequently misused and it should be checked. However, we found one exception. scsi/ipr.c intentionally ignore return value of strstrip. Because it wishes to keep the whitespace at the beginning. Thus we need to keep with and without checked whitespace trim function. This patch adds a new strim() and changes ipr.c to use it.

This preserves the queuing to threads for scaling out receive processing to multiple CPUs, but allows FCoE-aware multi-queue network drivers that direct frames to the originating CPUs to handle FCP processing with less scheduling latency. Only FCP is handled directly, because libfc makes use of mutexes in ELS handling routines. The bulk of this change is just moving the FCoE receive processing out of the receive thread function, leaving behind just the thread and queue management.
