* [SCSI] libsas: Delay issuing ABORT TASK TMF until the error handlerDarrick J. Wong2007-01-131-1/+2
| | | | | | | | | | | | | | | sas_task_abort() should simply abort the upper-level SCSI command and wait until the error handler to send the actual ABORT TASK command. By deferring things to the EH we simplify the concurrency coordination and eliminate some race conditions. Note that sas_task_abort has a few hooks to handle libsas internal commands properly too. Also rename do_sas_task_abort to __sas_task_abort just in case we really want to abort the task *right now* and we don't have a scsi_cmnd attached to the command. This is a hook for libata internal commands to abort. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] libsas: Enable the EH strategy handler to reset a phy after a commandDarrick J. Wong2007-01-131-0/+1
| | | | | | | | | | | When a SAS LLDD needs to request a device port reset, it needs to have all commands aborted before it can reset the port. Since commands are put on the EH's list in the order that they were queued, the LLDD can set a "need reset" flag in the last task to be aborted so that the EH can reset the port after all commands are aborted.

* [SCSI] libsas: Remove SAS_TASK_INITIATOR_ABORTED flagDarrick J. Wong2007-01-131-1/+0
| | | | | | | | | This flag is no longer necessary because we push tasks to be aborted into the EH as soon as we possibly can, and let the SCSI EH code take care of the coordination for which this flag was used.

* [SCSI] libsas: Add a sysfs knob to enable/disable a phyDarrick J. Wong2007-01-132-0/+5
| | | | | | | | | | This patch lets a user arbitrarily enable or disable a phy via sysfs. Potential applications include shutting down a phy to replace one lane of wide port, and (more importantly) providing a method for the libata SATL to control the phy. Signed-off-by: Darrick J.

* [SCSI] libsas: Don't give scsi_cmnds to the EH if they never made it to the ↵Darrick J. Wong2007-01-131-0/+1
| | | | | | | | | | | | | | | | | | | | | SAS LLDD or have already returned On a system with many SAS targets, it appears possible that a scsi_cmnd can time out without ever making it to the SAS LLDD or at the same time that a completion is occurring. In both of these cases, telling the LLDD to abort the sas_task makes no sense because the LLDD won't know about the sas_task; what we really want to do is to increase the timer. Note that this involves creating another sas_task bit to indicate whether or not the task has been sent to the LLDD; I could have implemented this by slightly redefining SAS_TASK_STATE_PENDING, but this way seems cleaner. This second version amends the aic94xx portion to set the TASK_AT_INITIATOR flag for all sas_tasks that were passed to lldd_execute_task. Signed-off-by: Darrick J.

Only after the call to unmap_mapping_range() are we sure that the page can no longer be dirtied. In order to fix this, NFS has hooked the releasepage() method and tries to write the page out between the call to unmap_mapping_range() and the call to remove_mapping(). This, however leads to deadlocks in the page reclaim code, where the page may be locked without holding a reference to the inode or dentry. Fix is to add a new address_space_operation, launder_page(), which will attempt to write out a dirty page without releasing the page lock.

So need of compiling the kernel for a custom address was gone. But Magnus uses vmlinux images for second kernel in Xen environment and he wants to continue to use it. o Restoring the CONFIG_PHYSICAL_START option for the time being. I think down the line we can get rid of it. Signed-off-by: Vivek Goyal <vgoyal@in.ibm.com> Cc: "Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the kernels later than 2.6.19 there is a regression that makes swsusp fail if the resume device is not explicitly specified. It can be fixed by adding an additional parameter to mm/swapfile.c:swap_type_of() allowing us to pass the (struct block_device *) corresponding to the first available swap back to the caller.

Userspace can check rflags, but the other cases or not testable under the current API. - if injection fails because of a fault during delivery. This probably never happens under normal guests. - if injection fails due to a physical interrupt causing a vmexit so that it can be handled by the host. In all cases the guest proceeds without processing the interrupt, reducing the interactive feel and interrupt throughput of the guest. This patch fixes the situation by allowing userspace to request an exit when the 'interrupt window' opens, so that it can re-inject the interrupt at the right time. Guest interactivity is very visibly improved.
