            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: linux-scsi@vger.kernel.org
          Reporter: Simon.Richter@hogyros.de
        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)
