* PM: Separate hibernation code from suspend codeRafael J. Wysocki2007-05-09
| | | | | | | | | | | | | | | | | | | | | | [ With Johannes Berg <johannes@sipsolutions.net> ] Separate the hibernation (aka suspend to disk code) from the other suspend code. In particular: * Remove the definitions related to hibernation from include/linux/pm.h * Introduce struct hibernation_ops and a new hibernate() function to hibernate the system, defined in include/linux/suspend.h * Separate suspend code in kernel/power/main.c from hibernation-related code in kernel/power/disk.c and kernel/power/user.c (with the help of hibernation_ops) * Switch ACPI (the only user of pm_ops.pm_disk_mode) to hibernation_ops Signed-off-by: Rafael J.

* dm log: fix resume failed log deviceJonathan Brassow2007-05-09
| | | | | | | | | | | | | | | | | | This patch removes the possibility of having uninitialized log state if the log device has failed. When a mirror resumes operation, it calls 'resume' on the logging module. If disk based logging is being used, the log device is read to fill in the log state. If the log device has failed, we cannot simply return, because this would leave the in-memory log state uninitialized. Instead, we assume all regions are out-of-sync and reset the log state. Failure to do this could result in the logging code reporting a region as in-sync, even though it isn't; which could result in a corrupted mirror.

| | | | | | | | | | | | The call to rh_in_sync() in do_reads() should be allowed to block. It is in the mirror worker thread which already permits blocking operations.

* dm raid1: fix to commit pending clear region requestsJonathan Brassow2007-05-09
| | | | | | | | | | | | | | | With the code as it is, it is possible for oustanding clear region requests never to get flushed when a mirror is deactivated or suspended. This means there will always be some resync work required when a mirror is activated, even though it may very well be in-sync. Always requesting the flush doesn't hurt us. This is because the log tracks whether any changes occurred and, if not, no flush is performed.

* dm raid1: one kmirrord per mirrorHolger Smolinski2007-05-09
| | | | | | | | | | | | | | | | | | | | This patch replaces the single instance of kmirrord by one instance per mirror set. This change is required to avoid a deadlock in kmirrord when the persistent dirty log of a mirror itself resides on a mirror. The single instance of kmirrord then issues a sync write to the dirty log in write_bits which gets deferred to kmirrord itself later in the call chain. But kmirrord never does the deferred work because it is still waiting for the sync write_bits. _mirror_sets is removed as it no longer needed, and we always flush the workqueue before destroying it to ensure all work is complete before destroying it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SCSI stack requires low level drivers to register and unregister devices. For zfcp this leads to the situation where zfcp calls the SCSI stack, the SCSI tries to scan the new device and the scan SCSI command fails. This would require the zfcp erp, but the erp thread is already blocked in the register call. The fix is to make sure that the calls from the ERP thread to the SCSI stack do not block the ERP thread. In detail: 1) Use a workqueue to avoid blocking of the scsi_scan_target calls. 2) When removing a unit make sure that no scsi_scan_target call is pending. 3) Replace scsi_flush_work with scsi_target_unblock. This avoids blocking and has the same result.

Typically, the ipr adapter uses the start BIST bit in config space to reset an adapter. Issuing start BIST on this particular adapter results in the PCI-E logic on the card losing sync, which causes PCI-E errors, making the card unusable. The only reset mechanism that exists on this hardware that does not have this problem is PCI Fundamental reset (warm reset).

| * | [SCSI] zfcp: Stop system after memory corruptionChristof Schmitt2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For each request that is sent to the FCP adapter, zfcp allocates memory. Status information and data that is being read from the device is written to this memory by the hardware. After that, the hardware signals this via the response queue and zfcp continues processing. Now, if zfcp detects that there is a signal for an incoming response from the hardware, but there is no outstanding request for that request id, then some memory that can be in use anywhere in the system has just been overwritten. This should never happen, but if it does, stop the system with a panic.
