            Bug ID: 88771
           Summary: No API to synchronize against SCSI bus scanning
           Product: IO/Storage
           Version: 2.5
    Kernel Version: 3.2.0
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: SCSI
          Assignee: [email protected]
          Reporter: [email protected]
        Regression: No

With the rightful demise of the scsi_wait_scan module, there is no interface left to find out whether any host adapter is currently scanning and synchronize against it.

With a kernel that has asynchronous scanning disabled, modular SCSI drivers and udev, this can be worked around by "udevadm settle", however that is not a generic solution.

Would it make sense to provide a sysfs object that an userspace program could use to synchronize against the end of SCSI scans?

You really need to discuss that on the mailing list, it's not a bug as such so this isn't a good place for it (and it'll just get lost)
