-OK, updated patch follows, with a changelog.
-
-I've added this check to user.c too, because that code can be called
-independently of the one in disk.c . Also, if resume is user space-driven,
-it's a good idea to wait for all of the device probes to complete before
-continuing.
-
-Thanks,

-Subject: PM/Hibernate: Wait for SCSI devices scan to complete during resume
-
-There is a race between resume from hibernation and the asynchronous
-scanning of SCSI devices and to prevent it from happening we need to
-call scsi_complete_async_scans() during resume from hibernation.
-
-In addition, if the resume from hibernation is userland-driven, it's
-better to wait for all device probes in the kernel to complete before
-attempting to open the resume device.
-
