* [SCSI] qla2xxx: Test and clear FCPORT_UPDATE_NEEDED atomically.David Jeffery2012-11-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the qla2xxx driver loses access to multiple, remote ports, there is a race condition which can occur which will keep the request stuck on a scsi request queue indefinitely. This bad state occurred do to a race condition with how the FCPORT_UPDATE_NEEDED bit is set in qla2x00_schedule_rport_del(), and how it is cleared in qla2x00_do_dpc(). The problem port has its drport pointer set, but it has never been processed by the driver to inform the fc transport that the port has been lost. qla2x00_schedule_rport_del() sets drport, and then sets the FCPORT_UPDATE_NEEDED bit. In qla2x00_do_dpc(), the port lists are walked and any drport pointer is handled and the fc transport informed of the port loss, then the FCPORT_UPDATE_NEEDED bit is cleared. This leaves a race where the dpc thread is processing one port removal, another port removal is marked with a call to qla2x00_schedule_rport_del(), and the dpc thread clears the bit for both removals, even though only the first removal was actually handled. Until another event occurs to set FCPORT_UPDATE_NEEDED, the later port removal is never finished and qla2xxx stays in a bad state which causes requests to become stuck on request queues. This patch updates the driver to test and clear FCPORT_UPDATE_NEEDED atomically. This ensures the port state changes are processed and not lost.

* [SCSI] sd: update sd to use the new pm callbacksAaron Lu2012-11-301-6/+13
| | | | | | | | | | | | | | | | | | | | Update sd driver to use the callbacks defined in dev_pm_ops. sd_freeze is NULL, the bus level callback has taken care of quiescing the device so there should be nothing needs to be done here. Consequently, sd_thaw is not needed here either. suspend, poweroff and runtime suspend share the same routine sd_suspend, which will sync flush and then stop the drive, this is the same as before. resume, restore and runtime resume share the same routine sd_resume, which will start the drive by putting it into active power state, this is also the same as before.

* [SCSI] scsi_pm: use callbacks from dev_pm_ops for scsi devicesAaron Lu2012-11-301-33/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | Use of pm_message_t is deprecated and device driver is not supposed to use that. This patch migrates the SCSI bus level pm callbacks to call device's pm callbacks defined in its driver's dev_pm_ops. This is achieved by finding out which device pm callback should be used in bus callback function, and then pass that callback function pointer as a param to the scsi_bus_{suspend,resume}_common routine, which will further pass that callback to scsi_dev_type_{suspend,resume} after proper handling. The special case for freeze in scsi_bus_suspend_common is not necessary since there is no high level SCSI driver has implemented freeze, so no need to runtime resume the device if it is in runtime suspended state for system freeze, just return like the system suspend/hibernate case. Since only sd has implemented drv->suspend/drv->resume, and I'll update sd driver to use the new callbacks in the following patch, there is no need to fallback to call drv->suspend/drv->resume if dev_pm_ops is NULL.

* [SCSI] sd: put to stopped power state when runtime suspendAaron Lu2012-11-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When device is runtime suspended, put it to stopped power state to save some power. This will also make the behaviour consistent with what the scsi_pm.c thinks about sd as the comment says: sd treats runtime suspend, system suspend and system hibernate identical. With this patch, it is now identical. And sd_shutdown will also do nothing when it finds the device has been runtime suspended, if we do not spin down the disk in runtime suspend by putting it into stopped power state, the disk will be shut down incorrectly. And the the same problem can be solved for runtime power off after runtime suspended case by this change. With the current runtime scheme for disk, it will only be runtime suspended when no process opens the disk, so this shouldn't happen a lot, which makes it acceptable to spin down the disk when runtime suspended. If some day a more aggressive runtime scheme is used, like the 'request based runtime pm for disk' that Alan Stern and Lin Ming has been working, we can introduce some policy to control this. But for now, make it simple and correct by spinning down the disk. Signed-off-by: Aaron Lu <aaron.lu@intel.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Rafael J.

* [SCSI] mvsas: fix undefined bit shiftXi Wang2012-11-302-13/+3
| | | | | | | | | | | | | | | | | | | | | The macro bit(n) is defined as ((u32)1 << n), and thus it doesn't work with n >= 32, such as in mvs_94xx_assign_reg_set(): if (i >= 32) { mvi->sata_reg_set |= bit(i); ... } The shift ((u32)1 << n) with n >= 32 also leads to undefined behavior. The result varies depending on the architecture. This patch changes bit(n) to do a 64-bit shift. It also simplifies mv_ffc64() using __ffs64(), since invoking ffz() with ~0 is undefined.
