From 6cdd55205d160f63003c321fcea608336953dd5b Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Mon, 9 Jul 2012 19:33:35 -0700 Subject: [PATCH] [SCSI] queue async scan work to an async_schedule domain This is preparation to enable async_synchronize_full() to be used as a replacement for scsi_complete_async_scans(), i.e. to stop leaking scsi internal details where they are not needed.
